We do agree that Bitcoin is the better version of gold. But gold investors won't agree with that and that's fine.
I'm sure it will overcome Gold's market cap in the future. Just you wait and see. If we don't witness such an event, our kids or grandkids will. Hopefully, Bitcoin survives way beyond the last coin mined.
Current gold's market cap is $23T and Bitcoin is at $2T. We'd sure see that someday that Bitcoin will overtake gold as the number one asset globally and based on its market cap. The price of Bitcoin by that time is gonna surprise the world of how high it is.
Even if it will, it won't be for long, imo, because the cap is everchanging.
Plus, we don't need it anyways to have all of the pros of BTC, so it's okay, but it would be a good point for those thinking BTC is a shadow coin of sorts or a Ponzi, I don't know who else would look at the caps to see what's good and what's bad
