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.
You are completely missing the point of my comment though. I am saying itβs immoral to buy property in excess in the first place. So it should be discouraged, disincentivized, or made illegal, yes, and there are plenty of ways to do it, and sure, that is one of them.
