Bitcoin blocks only carry a few thousand transactions every ten minutes. Even if we amp that up with more advanced scripting like cross input signature aggregation we wont be able to fit everything in 1+3MB. If we had 8 billion people on chain that would translate to every person making a transaction once every 30 years. You could increase the block size, but then you would need something on the order of 30GB blocks being sent every 10 minutes, data storage for almost anyone would be impossible so only a select few would be able to run nodes, killing our decentralization. Further, what would be the incentive to not keep increasing the block size and starving the miners of fees? You would end up with a very easy network to attack, be it nodes censoring or hashpower attacks.
