Ability to post as anonymous (doesn't show to average user who posted comment), with persistent hash instead of nick per thread (4chan style). Anon posts either shouldn't be able to receive sats, or sats should be handled on SN server side.

No we don't. If you want to censor people you can go to reddit and enjoy your safe space there.

Yes, as the number of transactions grow the resource usage will grow over time. This is a known concern and is being addressed by both ethereum and other blockchain devs. Mostly by the concept known as state rent or state expiry + more sophisticated data pruning algorithms. I mean we are not running out of space to store all the useless tiktok videos, we shouldn't be running out of space to store value transfers either.

Yeah, I think he refers to onion routing and how it's a bad thing that your transactions in such routing can't be monitored. Those people are beyond saving, they still can't understand that the definition of the crime has shifted so many times nowadays that the word lost all it's meaning. You want to donate to Canadian truckers without government blocking your bank account? Oi mate are you doing a lit' crime over here?

Social media, mainstream news, useless chatrooms, garbage computer games, all of them consume far more electricity than bitcoin and produce significantly less value.

Yes, that's how anti-fragility of data works, through replication, so that any bitcoin node can accidentally break it's ssd with ledger state on it and it will make zero impact on the network. Don't know what's dumb about it, bitcoin is much more secure than any traditional finance network, where else can you find a system where the state is backed up on >8k servers (nodes) ? I bet visa/mastercard has less than 100 servers of backups.
