You have no idea how any of this works.

Everything that you fear core30 “enables” was already possible from day 1 of this protocol.

You have no idea who is running core 30 or knots for that matter. Bitcoin is not a democracy. Your node matters to you and your transactions and matters very little to anyone else. A node that belongs to an entity with high economic activity matters more than your node.

Bitcoin is anarchy. It doesn’t recognize illegal content outside of what is or isn’t a valid transaction.
