I'm not assuming, I'm responding to a comment which defines a set of proposals, and that set of proposals does not include rent control. I can't really respond to your proposal of rent control, because it has no detail on how that would work (How would a newly build apartment building come up with rents that factor in their costs but not the 10% tax? Does any newly built apartment building just have to lose money every month?). But anyway, rent control is bad because it constrains supply of available units. That's been discussed on HN more times than I can count, so no point in rehashing it here.
