It really depends on what ends up being required. I'm already pretty much degoogled. I already can't watch age restricted videos on youtube and if it changes to require ID for any videos then I just won't watch youtube anymore. If ID requirements spread further to things like domains, email providers, etc then I may not have a choice because of my work situation. It could be that I have to find a new employer or career and rework my personal services to be hosted locally. From a technical perspective it's possible but it could be really uncomfortable.
