We really overuse these regulations. There are a relatively few buildings that are actually historic enough to warrant saving. But in many areas we're marking any old building as historic on the thinnest of pretenses. Having grown up in a city that was ruled by the historic review board, I'm unimpressed with the results. Maybe it's nice to see what they built 100+ years ago, but being forced to live in it forever? No. People change, neighborhoods evolve, we should carefully embrace that.
