Even with a security perimeter, a cantenna or yagi can easily bridge the
gap.

While you are correct that it's just as illegal to intentionally interfere

the FCC and regulatory bodies are much more likely to investigate and take
action against intentional interference in these frequency ranges than they
would be in the unlicensed wifi bands.
