Asbestos in the flooring of a house from 1972?

A curling can quite simply result from climate fluctuations because the top layer and the base layer are dynamically different. The adhesive’s strength was probably no longer adequate for the resulting forces at some point. Re-gluing should be sufficient in this regard. From my point of view, you’re making a bit too much fuss about the flooring of a non-living room.

It depends on the effort they put in during the process. I'm just saying containment, vacuum extraction, ... What do you say to that?

If that is simply ripped out without precautions, it would of course be a lot of money for little benefit. Then you could also take it out and dispose of it yourself with protective gear.

If I were you, I would probably have the entire basement done and then have peace of mind.

Edit: We ourselves also had some questionable or definitely harmful things in our 60s house. We got protective masks and suits, watered down the stuff at times to keep it calm, aired out a lot, packed it in big bags, and disposed of it properly.
That was okay for our conscience. My father once sawed asbestos boards without a mask standing in a cloud of dust. Yes, all that stuff is harmful and dangerous. But with a probability sufficient for me, not in small doses and with protection.

If it’s just torn out without precautions, it would of course be a lot of money for little benefit. Then you could also remove and dispose of it yourself with protective gear.

If I were you, I would probably have the entire basement done (have it done) and then have peace of mind.

Edit: We ourselves also had some questionable or certainly harmful stuff in our 60s house. We got protective masks and suits, dampened the stuff somewhat, made it very calm, aired a lot, packed it in big bags, and disposed of it properly. It was okay for our conscience. My father used to cut asbestos boards without a mask standing in a cloud of dust. Yes, all that stuff is harmful and dangerous. But with a probability sufficient for me, not in low doses and with protection.
