Ensuring you have counsel is intended to make sure that the government can't unfairly imprison/punish a person who is ignorant of the legal system and incapable of defending themselves. The end goal is still to be a check on government power.

That's still far different from the government being obligated to provide you housing.

(To be clear - I'm not taking a position on universal housing. It might be a great idea! I just think it's a different class of right, and I think the distinction is worth preserving.)
