If the UASF goes ahead and the miners reject it, the users will be stuck on a chain that they have no hope of creating a block on, since the difficulty is so high.
Would it be possible to make it exponentially easier to create a block, if one has not been found for, let's say, 1 hour ? (This would affect the actual miners as well, and make a block gap of greater than 1 hour 'basically' impossible.)
If all the users started mining themselves, on their full nodes, their combined hash rate would still be insignificant in comparison to the actual miners.. BUT.. who cares!.. As long as they can create at least a block an hour, and then for the difficulty to re-target, let's say, every day.. the Users would have a fully functioning chain after 24 hrs. Albeit, with a low hash rate.
Not only would they be able to function, they'd be making A LOT of money as they mined their chain.
I suppose if you're absolutely hell bent on creating an altcoin, you might as well go all in and make everything worse. I suppose you'll welcome the return of botnets and whoever is controlling the most infected systems getting the bulk of the block rewards? Yeah, sound
much better than the situation we have with the current miners.

Aren't you normally arguing that it's the stupid big blockers that were willing to throw the security of the system out of the window to get what they want?

As soon as the miners realised that all the action was on that chain they would join in, start making money again, and the difficulty would go back up..
That's just it, though. There wouldn't be "all the action" on that chain. People wouldn't want to risk it with such weak difficulty and the almost guaranteed 51% attacks. It's a pipe dream. I'm not saying that there aren't improvements that could be made to limit the risks of miner centralisation, but you seem to live in this fantasy realm where you can basically sack the miners and pretend there wouldn't be any ramifications.
Think about it carefully. Mining has been the equivalent of an arms race since the advent of mining pools and GPU mining. It's their business to find new ways to out perform their competitors. They do this 24/7, day in, day out. They've had years of experience now. So if you gave them the opportunity, they would
decimate a low difficulty chain like the one you're proposing. That, or they'd ignore it completely and leave it for the botnets, because it wouldn't be worth their time or effort.
the only thing the miners specifically do is make the chain. YES that's important. But.. MORE important is the user. the one who sends money over the network.
No, EQUALLY important. You can't have one without the other. It's a symbiotic relationship. Both are required to make it work, so stop pretending otherwise.
