What do you think about the argument that a fusion plant will cost at least the same amount of money as a fission plant to build and operate, so other than the PR issue, there would not really be that huge of a benefit to fusion if everybody just adopted fission now.

Not really sure where you got your information. I have worked in asbestos labs for over 30 years. Chrysotile was used extensively because it is naturally fibrous and friable. If you bind it into certain materials is will lose friability, but it can still be released (sawing through a floor tile for example). Chrysotile was used extensively as a filler in many materials. The most concern in finished out living spaces would probably be popcorn ceiling texture and the backing on linoleum, but the threat would be comparable to second-hand cigarette smoke. There is no general requirement to remove asbestos containing materials. The only rule is that in public buildings you most remove asbestos containing materials prior to renovation that would disturb the material (though many companies ignore this.) Chrysotile is less dangerous than the other types, but nobody really knows why. Chrysotile tends to be more silky or cottony while the others tend be more glass-like.

The legal definition of ACM has always been "greater than one percent asbestos" no matter the material. At the time they were not sure if asbestos contents below 1% could be accurately and consistently detected. A mineral must be a fibrous to be considered asbestiform, so chemical analysis is usually not sufficient. You have to use a microscope and observe fibers. Gypsum generally does not have a problem with asbestos contamination, though talc and vermiculite do. A much more common issue is the various building materials that included asbestos as a filler, often near 1%. Not to mention all the building materials still in place that have never been removed. The EPA has never required asbestos containing materials be removed - only that if they are in a public building and are going to be disturbed during remodeling, then they have to be removed using safe practices. Many, many companies ignore this requirement and spread asbestos contamination all over buildings during renovation procedures. Private residences have no requirements at all.
