Looks like you have fallen for metaverse, nft, trading hype from grifters who don't know their arm from their leg.
All these ideas existed for a long time, such as Cyber Town, Second Life and so on.
But children use the internet. People with very little savings use the internet. People with gambling addictions use the internet. There won't be any popular 3D virtual "metaverses" with risky trades and speculative gambling. It is bad enough we have this terrible trend the last few years.
In Facebook's hands? Crazy.
Remember the controversies over loot boxes and parent's angry about the financial gamification of their children. Then redefine your expectations.
