I think the dominant attitude in the US is to stick your head in the sand. Tons of older homes have asbestos yet almost zero of them report it in their listing or their disclosure report. If you test it and find it you have to report it. If the buyer tests it and finds it, the seller doesn't want to know because then they'd have to report it. Somehow knowing the house has asbestos lowers it's value significantly more than willfully not knowing + almost certainly having it anyways.

Happened to me. Bought a house with wood floors in the basement. We had some flooding which ruined the wood and when we ripped it out to replace, turns out the wood floors were installed over the original asbestos tiles. From what I can tell, the asbestos tiles themselves were of no particular danger to us, but once they got wet and started cracking they had to be removed which cost an additional couple thousand dollars on top of replacing he floors.

Yes because proper asbestos removal is very costly and people don't want to deal with it, your house is going to look like the government coming for ET. Very tempting for a singular homeowner to just read up and rent some ventilation equipment and rip it out themselves on the down low even if dangers are very real. There are some old mental asylums in my hometown, beautiful stone buildings on massive property, they have been sitting vacant and decaying for years because they are full of asbestos and no one wants to deal with it.

Yes, I'm talking about once you're at the DIY stage thinking "should I pull down that ceiling/wall myself? Should I even test it for asbestos?"

Nope, same attitude here.
