Parking minimums are a big problem. But, it's just a part of a much bigger problem: Regulation is strangling the life out of us. Regulation like zoning and countless other regs prevents market forces from working the way they should.

Have you ever heard of a banana shortage crisis or a jeans shortage crisis in the US? No you haven't. The reason is because market forces are able to adjust to changes in market demand. In housing, those market forces are bottled up and stifled, preventing investments, preventing innovation, preventing progress, preventing better solutions. We really really need to start looking at regulations and find ways to get rid of the ones causing all these problems.

ADDED: We've seen very little actual VC money or Research and development go into improving the cost of creating Shelter (In fact, we haven't made any improvements in this in the last 50 to 100 years adjusted for inflation). Much of this is due to regulations. Other industries can find ways to reduce cost but the mountain of housing regulations prevent any and all progress in these areas. I'd argue Housing is one of the most critical areas that human should be trying to progress in, as it's most important for human survival.
