No. I really don't want to shop around when I've been hit by a bus and need urgent medical care. I want to know that whatever hospital the paramedics take me to is going to be equipped to handle things, and that I won't be handed a crippling bill afterwards.

I also don't want to shop around for roads, police, fire service, garbage collection, or any number of other things provided by my taxes. I definitely don't want people less well off to go without those things because they couldn't pay. The point of taxes, and particularly progressive taxes, is to ensure everyone has access to services while placing the burden for that on those most able to afford it. That isn't particularly well implemented in many cases, but I strongly believe it should be the goal.
