I think not wanting to pay some yearly tax on that $1.4 million because the government pretends that the same as having $1.4M cash in the bank, or making $1.4M in a year, is fine.
Not wanting to pay the property taxes associated with a $1.5M home is the problem.
Which is why we also have things like a deferred property tax program! The way to "solve" the problems Prop 13 addresses would be to expand programs like that, but homeowners—disproportionately active middle- and upper-middle-class voters—want to have their cake and eat it too.
