There is a lot more to it than just making choices avaliable.
Let's say you are right.
I do not want taxes turned into a market. Doing that is a patch for not doing civics better in the first place.
When more of us get involved, the funding scenario inproves right a long with a lot of overdue things.
I am completely willing to revisit this idea when we are doing more of the basics right.
The cost of that would be relatively close to nil (except for those who'd rather you see you with no choice at all).
