Coinbase is shit for buying stuff. Use Binance or Kraken. Binance allow credit/debit card purchase but the best is always Istant SEPA, 0 fees and you receive the euro in few minutes max 1-2 hours, then you buy the coin.
if you want anonymity don't use btc, use Monero (XMR), Liska for what I remember accept that and if He doesn't he should be.
Monero trump anything in regards of security, and fees are super small as well.
