This is not to say that people shouldn't own their homes. I think in an ideal world, most people would own, or even all people would own and the market would just be liquid in terms of selling and buying. I think ownership has a lot of downstream benefits to communities, but by enacting so many policies to safeguard owning as an investment we've basically killed homeownership in the future.
Edit: 30 year fixed rate mortgages are just an example, there's tons of other issues. We've basically given homeowners the keys to power to fight back against any and all building developments. Zoning too is part of the issue, and is frequently used to fight back against building. If you want change, vote for a land value tax which is a good start to aligning incentives properly
