I'm a safe driver. Why should I have to pay for auto insurance? It's a wealth transfer to bad drivers.
... And actually, I completely reject your characterization of it as a wealth transfer. It's insurance. You have no idea if you're going to need it. You may be in a car accident and badly break your legs, and require corrective surgery and rehab. You may get pneumonia or a bad MERSA infection. If you haven't saved up a few hundred thousand dollars and you show up at an ER, then the wealth transfer is to you when the hospital eats the cost and passes it along to properly insured people. That's not even going chemo/surgery should you develop cancer, god forbid.
This is a stale discussion, but, auto insurance is not designed to be a wealth transfer to bad drivers. That's why you, as a safe driver, can pay a very small premium. Meanwhile, Mr. RacerX (with his super-powered sports car, speeding tickets, and an actuarial risk profile which suggests he is more likely to require payouts) will pay more.
More importantly, Mr. RacerX cannot call the insurance company from the scene of an accident, say that he needs auto care, and expect to pay the same rate that you do. Yet this is the financial equivalent of knowing that you have cancer, and signing up for a new insurance policy.
Finally, there's catastrophic health care insurance (which the ACA has more or less outlawed) which is in fact similar to auto insurance... then there are fancier plans with more coverage, which are more like warranty / service plans for your car. If you have an old car with 300,000 miles on it, it is likely to need more service or develop a crazy expensive engine issue than a brand-new car. If a warranty service plan or similar contract is available to you, you would expect to pay more for it. Likewise a human being, but the ACA has both mandated these plans and limited the amount that older human beings may be charged.
Please note that the moral rectitude, overall desirability, or similar characteristics of the wealth transfers associated with the ACA, or of other hypothetical wealth transfers or health-care related scheme... are not addressed by this post, which examines only financial structures. (The grandparent post examined only incentive structures.)

AFAIK, at least in California and I think this is true more generally, you don't. In order to drive legally on public roads, you must demonstrate the ability to meet a certain minimum amount of financial liability in the event that you are responsible for a collision either by posting a bond or by demonstrating that you have adequate liability insurance.
Most people choose to meet that requirement through insurance, because it has a lower up-front cost (though likely higher lifetime cost), and because they also want other coverage besides the required liability coverage along with it.

It is insurance, but rules like the "no exclusions for pre-existing conditions" and controls on what factors can be used in rate setting also make it a wealth transfer. (At least part of the idea of making it a wealth transfer is to improve overall access to insurance and, through that, preventive care, to make the overall system more effective for everyone.)
The subsidies are to poor people. The poor people get medical care anyway, at ERs, where hospitals cannot refuse them. Or they forgo the care until mundane problems become chronic or acute problems (and they end up in the ER). ERs happen to be the most expensive means of providing heath care. So, to answer the first part of your question, the subsidies exist so that people who cannot afford heath insurance via the exchanges can still have health insurance. And the reasoning behind it is to reduce health care costs that emerge from lack of access to care.
I know less about the age rating bands. Off the top of my head, it's to smooth costs over a lifetime. So it's a wealth transfer from your young self to your old self, if you have typical health care costs over your lifetime: http://www.ncbi.nlm.nih.gov/pmc/articles/PMC1361028/
There are massive subsidies going to the 50-64 years of age crowd.
Now, yes, you can argue that it's good to smooth costs over a lifetime ... but that also hits the young very hard when they can least afford it. As does their FICA taxes for Social Security and Medicare.
As we've seen in pretty much every other developed country, this whole welfare state approach is a self-correcting dead end, as enough of the young decide not to play the rigged game and decline to have children.
Mandatory coverage was another wealth transfer; when 30% of patients are not paying for their medical treatments, and the other 70% are being forced to cover that cost, it is a wealth transfer.
To be clear, I am not saying wealth transfers are bad, but we should be honest about what is happening.
I do see where you're coming from. Maybe if I said I don't believe it's a _new_ wealth transfer? 30% of the population is not going without care today - they are getting ER care for non-emergent reasons or they're covered by Medicaid or the VA. The Medicaid/VA is a direct cost and the ER visits are indirect via increased costs.
Unless we want to decide as a country to not subsidized healthcare for those that can't afford it and to allow hospitals to refuse treatment without upfront payment... then let's be honest about what's happening there, too. The money comes from somewhere, it's every bit as much of a wealth transfer.
