Assuming Thailand will crack down on those temporary remote workers, they will just go some other place.
EDIT: fixed typo.
They are rightly wary of western power being exerted now through corporations rather than through a military, because that's how things work these days, so they limit the ability for western companies to make inroads here. (For example the local Shell, Esso, etc. are all technically wholly owned by Thais.)
Obviously this concern doesn't apply for freelancers and small businesses whose clients are in the US, but those folks aren't numerous enough to affect immigration policy.
Limitations such as max 95% foreign ownership (Indo) end up with local lawyers or accountants owning 5% of the companies that are set up and are figureheads there to fulfill government requirements. Or in Thailand where many industries are only open to Thai nationals, which means the only way foreigners may access those industries is through marriage, though when those marriages dissolve so to does the foreign claim on business assets.
I don't blame them for making it difficult for foreign investment dollars to pour in and displace domestic ownership, or for not embracing western capitalism as fast and as hard as they can.
49% foreign ownership max, unless you are American.
