Right, but this is not solely about cookies or blocking ads. You also leave behind data which helps create a profile. AI is mass-creating profiles of everyone. Not everyone will have the same pattern, but information space is finite and they get more and more data about you over time. You may think this is not relevant for your use cases, but can you make this as prediction in the future?

The future of myself and my son does not depend on nor benefit from my anonymity.

I'm not a revolutionary taking up arms I'm a voter and a citizen in disagreement. Unless I am seen and counted, then being any of those things is worthless as well.

There is no value in hiding from the system while the system goes to hell and attacks everyone else.
