The only logical path forward for this blockchain technology is to start using some governance protocols to secure and effectively decentralized territory in the real world. Just look at how the current world works the banks are at the top the banks run the government's and then the government's have authority over physical boundaries and have the Monopoly for physical violence.
The only thing we need to be focused on to really move crypto forward is finding ways to anchor governance protocols into the real world. This is in fact the scaling solution because once we're able to effectively decentralize territory we can then put data centers and routers in this decentralized territory and now you're scaling is only limited by compute speed processing speed
The blockchain technology can be either centralized or decentralized which is subjected to the one we are talking about, if it's bitcoin it's decentralized and nodes are all around the world where as if it's CBDC its under the control of government probably under central bank authority so blockchain is just the technology and it can be used in the way we want.
As of now the world is divided by boundaries so called countries and each of them are controlling by their own laws and leaders so it's impossible to get them United just because of decentralized monetary system.
