That again is a technological problem. Web infrastructure providers rely on CAPTCHAs because nothing better exists once you take away browser fingerprints. Zero-knowledge authentication would enable a browser to prove to a server that it's being used by a legitimate user without compromising privacy or forcing its user to perform CAPTCHAs. But these technologies cost money to develop, and this is where the government can step in. The cost, while great, should be compared to the labor and innovation costs of imposing regulatory straightjackets like GDPR on everyone, which are hard to measure, but undoubtedly enormous in the aggregate given the pervasiveness of their effects.
