One interesting side-effect is the rise of the edible straw. There are other edibles as well, spoons, forks, knives and bowls - though the latter is rather an old idea.
So while the ban straws was a token gesture it does seem to have generated some creativity and movement on other fronts which at least gets peoples attention on the problem of single-use plastics.
Even if the only the thing the straw ban did was inspired a whataboutism movement to pretend to care about fishing nets, it would still be a net win in terms of motivating improvement.
