To get around the obstacles most kids will need a very motivated parent who can advocate for them with admins, and that basically will just harm kids who's parents don't have the time/resources/charisma to make it happen for their kid.

This is semantics, no? Couldn't the obstacles be so large that it's practically the same as forbidding?

When I read "they're not forbidden", I take that to also mean that there's few new obstacles.

This is a classic tactic. How many trees do you need to make a forest? How many pebbles make a dam?
