Data will always be the most valuable asset, with or without the Internet (TCP/IP makes it easy to move, but is not required).
Once the 2-way links are available, running your own node without meshing would likely be a requirement for retail shops, miners and investors that will help grow the footprint.
If they could code liquidity modes into wallets (ie. Spendable vs not spendable modes), they could possibly limit the losses during disruptions by having wallets that are in a non-spendable state stay safe from manipulation, while only the crypto in spendable state wallets that are in circulation being vulnerable to loss or fraud during catastrophic events.
I think something like that was proposed with one of the alt-coins a few years back.
