I still don’t understand the answer to this question: “What prevents people from having their own UTXO now? There are more bitcoin addresses than stars in the universe.“
It's the number of transactions that can generate a UTXO with Bitcoin in it. There are a limited number of transactions per block. This can't increase, more demand raises the price and makes it unaffordable for some people.
And I collected the amount via a L2? I think I understand what you’re saying. I’ll think about it.
