The idea satoshi had for scaling was "just turn most of the userbase into SPV users", but that's part of the design those who run a non-mining node seem to disagree with (so take it up with them, collectively, because that's not my fault). They don't have any desire to be relegated to SPV status against their will. We also need to take into consideration how mining became centralised at a pace far greater than satoshi anticipated.
If the only cost to consider was the cost of transacting, you would have won the argument years ago. But you're only looking at half the cost. The cost of running a non-mining node is now a vital consideration. That cost also needs to be affordable for those in less prosperous financial circumstances. Why do you think it should be full nodes for the wealthy and SPV for the poor?
There is a balance to be struck between cheap transactions and cheap independent validation of those transactions, without needing to rely on third parties. Both are equally important. Stop giving in to your bias that only one side matters. It's ignorant and dangerous (but then, that's just franky1 in a nutshell, isn't it).
Build a time machine and go back to 2017 if you want to dispute any of this further. This is not a scaling topic, so stop turning it into one. It's over. You lost the argument.
//EDIT:
I made no reference whatsoever to "mining costs" in my post, so I don't know what new and baffling tangent franky1 is embarking on now in his following response. I was talking about the decentralisation of the network. I honestly don't know if franky1 didn't pick up on this because he cares to little about decentralisation that it doesn't register in his brain. Or maybe he suffers from a learning disability and can't read. Either way, any further responses directly to franky1 will only lead to further topic derailment. He couldn't stick to the subject at hand if his life depended on it. All he does is disrupt threads with incessant nonsense and gibberish. Avoid engaging with him directly. He's not worth wasting your time on. I would strongly encourage everyone to place him on ignore.
