Monero blunts this at the network layer with Dandelion++ , which relays a new transaction along a random stem before broadcasting it widely, so the true origin is obscured. For stronger protection, use Tor (this site runs an onion service). On and off ramps. A KYC exchange knows the coins are yours when you buy or sell. On-chain privacy does not undo identity collected off-chain.
