These sound like bold claims, honestly. I have never lived in a rent controlled area, but I have also never had the money to enter into the only rent controlled areas I know of. Such that it is easier for me to understand the possible negatives of rent control over the positives. Do you have good reading on why they are false? (Basically, your moral argument sounds like I could see the appeal, but mostly false. Whereas the other arguments lack any appeal to morality, but seem much more likely.)
