Earlier quoted context omitted.
Wouldn't it be better if we were allowed to interact voluntarily? Pay for what we wanted and used, and support people and causes through charity instead of under duress?
No, it wouldn't, because that's the fantasy that libertarians always push that has no historical or contemporary basis for working as a society. Sorry for being grumpy, but this is as useful a contribution as "Wouldn't it be better if we harnessed the power of house-elves to magic away our trash?"
To extend your analogy: "The magic house-elves are already making our cars, writing our software, and growing our food. I wonder if we should pay them a bit more to cart away our trash too."
The house-elves shouldn't be doing the law enforcement or the Government (and in fact they _are_ right now, e.g. in the case of for-profit prisons and the Fed, and it's a disaster). But they're a bit under-utilised right now in some areas :)
