Hmm, looks like I did link the wrong article although nothing in the article I did link says these effects are positive.
Here's the paper I originally quoted - the effects of prop 13 are extremely bad.
This is not a unique finding either, the literature about how prop 13 is bad is robust because it incentivizes things that make no economic sense to incentivize. It's just another attempt like rent control to make up for housing policy failures with poorly targeted band-aids. The reason people were 'taxed out of their home' is because bad housing policy sent prices skyrocketing. Instead of fixing the bad housing policy people decided to make it so you were protected from those effects as long as your turtled in your home, even if you didn't want to live there anymore.
Dumb, dumb, dumb.
