No Kings isn't for Trump, he's too stupid and self-delusional to understand anything. It's for all the other MAGA leadership, who are quickly understanding that it is all falling apart at an increasing rate. Once you have major supporters openly condemning them, it's over.

No Kings isn't supposed to do anything but demonstrate opposition numbers, and since each one grows larger, that is making a HUGE psychological impact on MAGA. Many got on board MAGA because they thought it was the winning side, and they want to be winners. When they see that they are on the unpopular side, many will walk away from MAGA. NO Kings helps drive that home to these dipshits.

It also helps energize those at home, who think MAGA is in total control, and there's nothing they can do. No Kings demonstrates to those people that they aren't alone, there are millions of others fighting for them.

What do you think those people should do instead?

What are you suggesting here? The no kings protests have shown how the opposition to this tyranny can be shown peacefully rather than through violence. Any publicity is good, its spreading the message in a peaceful manner and changing peoples mind to the regime without violence. Thats pretty good, really. Sure it's not changing anything over night, but at least they're building momentum and doing something rather than nothing at all.
