My point is more housing stock alone would solve many issues, just not this one. It’s the same reason sound insulation which most people care about isn’t directly measured when renting or buying an apartment, you just don’t know upfront. Now if there was a lot of housing stock, and apartments were forced to include expected utility bills / apartment to apartment sound transmission level that would help.
