Crusty Old Meatwad (he/him)
That's a fairly blatant False Equivalence. Wind blowing an object on the ground does not equal the wind blowing the same object while it is suspended. Try it some time. Take a small flower put and put in in decent wind. It won't move on the ground. Now suspend it by a thread in the same strength wind. It will move.
Wind blowing against a man sized object suspended on a wire also does not move the man like he's weightless.
Now can we talk about the rules and magic, as opposed to physics? There is nothing in the text of the spell which says you are weightless. Weightlessness, even in just one direction, would have a lot of ramifications for other rules and would have to be in the text to have that effect.
