I don't disagree that every policy has some downsides. For 1 and 3, though, People driving around for a long time to find a parking space is a sure sign that parking is too cheap. The ideal parking price, according to Donald Shoup, is one that leads to there being an average of 1 empty space per block. That does mean that pricing has to adjust according to time of day/day of week, and probably be higher during special events. And that does have the downside that, well, parking is more expensive. But I think the benefits far outweigh the costs, as driving has a ton of bad externalities, especially in cities.
