I think domestically we need some analog of the EU's GDPR, as table stakes for preventing the surveillance industry ("big tech") from amassing so much power over the People that they're inclined to try for another coup.

We also need some kind of antitrust enforcement against the forced bundling of products from the distinct categories of hardware devices, network services, and client software.

Those should leave us with a similar environment to the EU. Beyond that, sure tax away, whatever. If we've done our job right domestically, these services should be a lot easier to value in terms of subscription fees rather than nebulous values siphoned away from surveillance subjects.
