> How do you imagine YIMBY relaxing zoning and allowing things at lower cost and not simultaneously allowing people with money to push through what they want?

Relaxing zoning laws never meant throwing them completely out the window. It has always been a matter of pruning zoning rules that overly restrict land use to the point that minor deviation from the norm is impossible.

Whatever the level of relaxation, I don't understand how you think it is going to enable low cost development of your preferred things, while excluding those with money from absolutely pushing rules to their limits to build their preferred things..?
