Those are words that are low in epistemic legibility.
I look at metrics to arrive at my opinions. Things like the difference between the number of new housing per capita in various cities in California compared to Austin, Texas. Things like the R^2 when you do a linear regression of the amount of new housing per capita against changes in rental inflation.
I can't really follow your comment but new housing costs a lot because we now have high standards for what can be legally rented for buildings with more than 5 units.
The housing I was describing as plentiful is a mixture of existing housing as either standalone or fewer than 5 units.
