You're completely missing the point of the comment you're replying to, though.
The parent comment suggests that the cost of investing is not high enough. Moreover, they suggest that it should not only be a higher cost, but that this cost should be redistributive.
The proposed cost isn't redistributive, though. The investors aren't running a charity, and there's an inelastic supply, so they'll be passing the cost of all of those taxes on to the renters until they have a comfortable margin again.
