well if we're going this abstract then everything everywhere involves "other people".
Pragmatically mining, even through a pool does not show who you are or who you are associated with as no one can associate you with anyone if they can't associate your coins with you.
This idea that exchanges will stop handling coins from flagged addresses is nonsense - DEXes already solve that problem anyways, so an exchange will be willingly giving up business for legit customers who may have happened upon a coin with a less-than-legit history and they'll do nothing to prevent money with illicit history from making its way onto their platform.
