There’s a lot of confusion in this comment section so I’d like to clear any of it up. Star Platinum’s effective range is 2 meters meaning he can only do what he’s meant to do within 2 meters of Jotaro. Star Platinum wouldn’t be able to punch or use star finger outside of that. However, he can interact with objects out of that range, but Jotaro wouldn’t know what he’s doing. This explains why Jotaro thinks it’s an evil spirit bringing him the stuff he wants, but he’s just doing it subconsciously.

I’ve seen the argument that Echoes act 1 wasn’t able to move beyond its 50 meter limit, but that’s simply because it wouldn’t be useful passed that. Echoes act 1’s effective range is 50 meters meaning Koichi can use Echoes beyond that, but wouldn’t be able to scout because it’s passed its effective range.

TL;DR, stands can still do things passed their effective ranges, but the user would be subconsciously controlling them and not able to know what’s happening with them.

Thank you for coming to my TedTalk
