Maybe. I mean you can't control who gets into bitcoin. And no one knows what's going to happen. If we really get hyperinflation in the fiat system, the people holding the ETF's will suddenly realize why its best to hold your own keys.
I do see the point though that if you're holding your keys and you have your portion of bitcoin that can never be debased, it might just be good enough. Its just that we see and hear all the "revolutionary" and more radical opinions here, nostr and X. The majority of bitcoin holders might have a completely different view.
