More conclusive (at least for me): you switch a light bulb on and off;
after infinitely many steps, is the light on or off? (Or: you put one
and the same ball in the vase, out of the vase, in the vase, out of the
vase, etc. What's in the vase/where's the ball after infinitely many steps?)
If you can't trust supertask-reasoning in this case, why should you
trust it in other, seemingly less problematic cases?

For the sake of clarity: I'm not endorsing or advocating the
backward-supertask paradox as extremely important. Just wanted to share
it here, because I had never heard of it, and thought perhaps others
also hadn't.
