alt Hacker NewsMeshtastic works on commercial frequencies. If they block those then a good number of non-wifi/bluetooth devices will just stop working.
Including, but not limited to: garage door openers, some (older) car key fobs, some RC equipment, wireless weather sensors, remotely readable metering devices (electricity, water) and a crapton of other things.

Nah. The citywide meshtastic grids that exist presently operate on one single frequency citywide.
If you shut off the internet and jam that frequency, nobody can talk to anyone else to coordinate about a new frequency (which is then also just trivially jammed).

You could just flood Meshtastic channel with valid traffic specifically

All Semtech LoRa modems are wide-range modems. You can switch to basically every other frequency.
An idea would be to move to SX128x modems with work around 2.4GHz. You recycle Wifi-gear for directional stuff. This also enabled you to hide below Wifi traffic.
Still jammable - but much much more difficult.
