I mean, if the point is to remove street parking, I'm in favor of that.
I don't think there should be any real government intervention to then create additional parking, though. Seems like a move in the wrong direction.
What I think would be good instead, though, is ending parking minimums and then declaring that businesses cannot restrict who parks in their lots to only customers. They can charge a fee for the use of their lot, but otherwise anyone can park there for any amount of time. This would vastly expand the amount of long term parking, drastically driving down the price, while also incentivizing landowners to now redevelop their parking lots into something useful
