As long as you have SM not much is permanent.
What is stopping you from strapping some explosives to the stabilisation module or firing a few missiles?
RP all the way!
The fact that blowing up the stabilization module (which is a ship or station component, not an unmodeled fiction element) doesn't in any way un-stabilize the jump points it has previously stabilized?
You can RP quite a lot of things of course, but the jump gate to point stabilization lore change seems to directly speak to how the pathways aren't something you can just blow up.
On the other hand, I'd suggest that the hardware that can stabilize the jump point probably could be reversed to destabilize it. It might take the same amount of time as stabilizing the point would, but that arguably makes the exercise more interesting - if you want to sever the highway you'd have to hold the cut point secure for months while the demolition gets done.
