BSV, BCH etc are all irrelevant, talking about GB blocks is also irrelevant to Bitcoin block size discussions, no one is stupid enough to actually think about anything above 100MB by 2030. So I think bringing GB is bad, it makes mining centralized etc is a fallacy.
I don't know who you are but it seems you have a few pockets filled by recent spam attacks and you are trying to deviate from the actual concern, which is ; Bitcoin has to scale. I would say if we had 8MB blocks, we could hit the walls of $80,000 by now, but that's just speculation right?
