>it might be time for space satellite hosting companies.
Uhm that would probably backfire and make you an open target for every security service on the planet.
German BND did bulk-collection on satellite communications, even tho German law does not allow for something like that. So BND reasoned "Satellites are in space, German Grundgesetz does not apply in space!", dubbing it the "Weltraumtheorie" (Spacetheory)
Afaik this whole "satellite/international water" scenario was suggested to prevent government agencies from forcing access to sensitive data trough legal means.
If your data is so insensitive, that you can have it just sitting there accessible by anybody, then you might as well just put the data on regular public servers and not bother with the effort of building a "space server".
