The basic premise of this post is "the key edge that you have over your worldwide competition is that you are local". That premise is false, or at least heavily overblown.

If the only detail barring you from working for a company which otherwise totally really would hire you, then there are often times way around this already. I moved half-way around the world for my current job. My competition was therefore people from all over the world. My job won't be "taken" by "anyone" now more than pre-Covid.
