"the wrong path to being the next San Francisco"

But San Francisco has had rent control for years, yet this is the same policy people are advocating.  If you don't want to become the next San Francisco, why on earth would you rely on the same policies that turned San Francisco into what it is today?

What San Francisco has in spades is an anti-development zoning code and general mentality, which prevents new housing (including affordable housing) from being built.

Inclusionary zoning combined with easing zoning restrictions (e.g., parking requirements) for certain types of residential construction could go a long way towards increasing affordable housing *and* creating the density/walkability that promotes sustainable living practices, and is the best place to start at this point in Portland's transformation.

Starting with rent control and anti-displacement measures will just get you to San Francisco status sooner.
