I'm probably a lot better informed than you are about zoning concepts and issues. There is bad zoning and good zoning. R-1 is terrible, SW-SAZ is worse. S-C and S-JW are pretty good.

Protecting established neighborhoods is _essential_ to compact growth and housing equitability. If you haven't figured that out yet, do some more real-world learning.

You don't appear to have paid attention to the examples of the work some of us have done to remove roadblocks. That can be done intelligently, which SW-SAZ did not.
 
You also didn't seem to pay attention to the issue of the way compliance with statutory housing capacity requirements drives what kind of housing you get. More evidence that you haven't done your homework. Without understanding these mechanics, screwing with code would mainly do only harm.
 
If you're active as an advocate, you _really_ need to become more informed before trying to take the wheel.
