The OP is not accusing Caucasus of stealing, he says people shouldn't trust physical coins. Even if you buy a Caucasus coin from someone, the seller could have peeked behind the seal, using the right equipment, especially if BTC price is high.
That's true. I took issue with the idea that Cas should be shamed for not spending his time promoting alternatives when he's providing a legitimate good where the operator's never really done anything wrong. Taking issue with trying to make Cas a specific target, I didn't address the real message. Cas' model is terrible if you don't really trust the person issuing the coins.
