I would gladly pay for an extra spot, and I'm sure developers would build more monthly garages a la NYC.
It's super hard to convince all those single family home owners at meeting that I actually like density, and choose to live in the densest part of my city because I like it. I'm not alone, there are a lot of us! But others prevent us from living in our preferred way for no good reason.
Not building parking spaces in LA would be denying the realities of living there.
Refusing to allow people to go carless has a predictable result, that is self enforcing. I would say that "denying reality" is when people refuse to allow others to be different from them.
And it's not just LA, it's the entire state.
