It’s not always the case that builders provide parking. The market demands shareholder profits, and if you don’t build a driveway, that’s more units you can fit on a given plot of land.
This is the trend I’m observing, but I’m certain it is not universal. 
Parking is for residents. If they want more parking, they can pay for a property that has that, which will usually cost more. If not, they can pay less and go without. This is a good thing and it’s not something the government needs to involve itself in. Right now the vast majority of places (in the US at least) have a really excessive amount of parking, so it may be that segment of the market is temporarily saturated, and they’re building for a market that wants less, which has gone unserved for a long time due to these pointless laws.
