For Europeans at least there is now a non-KYC way to easily buy bitcoin: https://relai.ch/

I think that surveillance on Bitcoin is all just pure guesswork and FUD. Example: someone first sends a transaction from any exchange that requires KYC. They receive the funds on their wallet (let's say Bitcoin Core) and they send just this UTXO on-chain to yet another address. By surveillance this could have been decoded as:
  1. Buying bitcoin and sending it to themselves with one extra hop.
  2. Buying for a third-party without disclosing their identity.
Surveillance can also correlate different UTXOs (some of them with a clear KYC trace) if they appear as multiple inputs in a single transaction. But still they can just guess on what happens to the transaction output.
Practice: One can buy no-KYC straight from a friend or move only whole UTXOs or use coinjoin.
No idea what peel chains or wallet clustering means.
