Running steel cable or nets, instead of monofilament wire, is pretty much SOP for denying an area from rotorcraft. There's a pretty cool article on Wikipedia about prison escapes by helicopter [1] that explains how this is often implemented in high-security correctional facilities.

I like it how there are green or red helicopter icons in the table to indicate success or failure.

Yeah, somebody had fun with that article. It's one of my favorites on Wikipedia.

But then you don't get the reusability, unless you have spools and can cut the lines, which probably gets you back to the weight of a net.

A modern version of barrage balloons.
