The natural response to this might be that, of course, you should be able to live on an SFZ lot with a big yard and lots of distance from your neighbors. You just shouldn't be able to enforce that condition within walking distance of Palo Alto.
I agree. I’m not even defending Marc here, which seems to be how my comment is perceived so obviously I didn’t articulate the way I wanted to. I was responding to the GP’s sentiment of density becoming the new desired standard. I’d prefer availability of less dense neighborhoods in at least some capacity.
