Not everything advances. We still have houses built in the 1800s/1900s that are usable in predictable/similar climates/circumstances. A changing climate changes that.
Sure, we could bulldoze everything and build new stuff that can handle a +2C, +3C, +4C, etc... world, but that's expensive.
There are 2b+ people living in "inadequate housing", don't have sewers, don't have running water right now, we can't even fix the problem now, we're not going to fix it better when 2b more need AC to survive every summer

It's not just expensive. Steel and concrete are some of the largest drivers of CO2 emissions and toxic waste, in the ballpark of 15%! So really the only sane choice is to avoid building new homes whenever possible and try to keep old houses in use as long as possible.
