So already, I'm seeing this draw pretty solid legal challenge at a fundamental level: namely its a violation of the 5th Amendment "...nor shall private property be taken for public use, without just compensation".
See Supreme Court case ruling in Stop the Beach Renourishment Inc. v. Florida Dept. of Env't Prot. (Scalia, Roberts, Thomas, Alia) - "...if [a branch of government] declares that what was once an established right of private property no longer exists, it has taken that property, no less than if the State had physically appropriated it or destroyed its value by regulation. '[A] State, by ipse dixit, may not transform private property into public property without compensation.' "
I think we should all be financially prepared to engage this to the best of our abilities, but I would anticipate this either modifying some way (ie, through provisions to landlords) or to be removed and replaced with a more sensible alternative. This simply won't stand from a legal perspective.
