This is exactly the problem. Lots of people love low or medium density cities because they make great places to live. And then other people who want the same thing start moving there, not asking what made it great in the first place. When lots of people do that, the prices go up and then the newcomers demand that they be accommodated at whatever price they want. Also the hate against rent control here is myopic. Rent control is meant to protect those incumbents who were a part of the community prior to rapid growth / increase in prices. It allows low supply (protection of quality of life) to work without displacing incumbents when faced with rapid growth. Now we can argue about how effective specific implementations if rent control are, but a lot of folks misconstrue the underlying goals.
