Then you don't have to use it. You can issue limit orders instead of market orders as described in the post that started this thread. Lots of people do want to purchase liquidity though which is why these folks exist.

(In reality, assuming you're a small retail investor, you don't even have to do what this blog post says. Your transactions are small enough they aren't going to hit the exchanges anyways.)

I know exactly what you mean with this comment, but the idea that anyone can "opt out" of the current markets is ludicrous.

I wouldn't attempt to sell titanium to the Amish for the same reason that no rationale investor attempts to sell stocks without the existing market maker system.
