[Avengers Endgame] When they went thru time, the Avengers all wore nanotech armor that transformed into their costumes and gear and allowed them to shrink/grow. So during the final battle with Thanos, couldn't they have all just grown to giants and attacked Thanos' army like Godzilla leveling Tokyo?

Not everyone can just grow to be a giant and still be able to operate for more than a minute or two. Goliath couldn't grow anywhere near as large as Scott. And Scott took quite a while to be able to grow and be able to fight.

This is like when people ask "why doesn't everyone have a pair of Falcon wings" - because most people would kill themselves using it.
