I'd argue that people end up gravitating towards anarchism because they desire personal agency, and I would also argue because western society conditions people to become atomized and see things from individualistic perspective. So these small organizations and flat structures become appealing from that perspective. There's also an aspect of defeatism to it as well where people can't really see the system being challenged and they start focusing on carving out something for themselves within it, like making a commune. It's not about broader liberation, it's just a way to solve a personal problem.

And this explains the phenomenon of anarchists adapting to a socialist state once others do the heavy lifting of creating it. The new social conditions are more conductive towards making communes and other types of organizations anarchists desire. So, in a way the hostility anarchists have towards Marxism-Leninism is itself strange. If they're willing to live under a capitalist system and try to carve out spaces for themselves within it, then doing so under a socialist system would surely be easier.

I do think that if there was a serious ML movement in the west, a lot of anarchists would in the end align with it as they have in the past. Part of the problem is that it's all largely theoretical right now with the conditions being what they are.
