We are not.

You don't get to place your Loran-C jamming car right next to the supertanker
or cruise-ghetto, nor will any major airline allow your semi/van to emit EMI
from the parking-lot for long.

The problem with GNSS is that you need so little power and antenna to deny
such a large area.

VLF just doesn't suffer from that.

And now that US killed their LORAN, maybe we should apply some modern
signal-theory and design a new and even more robust VLF signal...
