You have to be joking. If anything he made himself look foolish claiming bitcoin actually has the capability of defeating the gold market cap. You've made how many threads yourself saying bitcoin has no future? Now you're just randomly taking the exact opposite stance even though you know it's wrong.
We are not joking and we know we won that point emphatically and you looked so silly.
There are many details which you fail to assimilate. For example, you are conflating Bitcoin with crypto-currency and decentralized networking technology in general. Napster wasn't the end of file sharing.
File sharing is orders-of-magnitude more used now than it was no long ago during the peak of Napster. That is what will happen to gold's market cap, which btw is 3-4 orders-of-magnitude overstated if we are talking about the physical gold traded by the goldbugs. Nearly all of the gold is controlled by the elite.
