well sure, but it still allows for huge blocks to be handled by home users, they just have to be able to stream data at ~1MBPS to handle >4,000TPS
Why on earth would they?
Everyone on earth should be able to handle the same txs as VISA just so you can buy your coffee?
I think you forgot to ask everyone on earth if they want to (and most smartphones which are going to be the majority of computer users are going to literally start burning a hole in your pocket doing that).
