Is the comparison intended to discredit gold? It sure is. Does doing so lend btc at least the legitimacy of the asset it is compared to? It sure does as well.
Yeah, the obvious pathway for bitcoin to become very valuable in the medium-term is for people who own gold as an investment to realize that bitcoin is really idealized gold (with various other upsides gold does not have), and therefore, that they probably want to transition some of their gold allocation over to bitcoin.
Incidentally, that value-boost to bitcoin would enable more of the other international trade, remittance, forex liquidity, etc, that bitcoin can theoretically excel at.
