If you follow the rules. Presumably an attacker wouldn't care about that, and would be happy to dump a few orders of magnitude extra power into their jamming signal.
Yeah, and if they had gasoline and matches they could go around and burn down everyone's houses. The point is that the protocol shouldn't have a flaw that allows local traffic to have harmful nonlocal effects.
I think FCC still cares about jamming signals, although they might make an exception for inexpensive mesh networks...
With a mesh network, the network is much bigger, which makes it important an attacker can only disrupt their small corner of the network.
