My concern is that the physical layer is more limited and is indeed disrupt-able / controllable.
We need some neutrino transceivers. And a few other orthogonal communication technologies.
Edit: I guess it is also a comment on the situation that I deleted my comment before reconsidering and deciding to repost it.
When opinions can no longer be expressed without fear of (arbitrary and/or extra-judicial) retribution, things have really started to go too far.
The physical media are too constrained. Even if you're not into "black arts" (and I'm not), you may have increasingly limited trust in the powers controlling the infrastructure (not so much the engineers, but the people who pay them and/or put them in jail).
We have amateur radio (pirate or registered), AX25, APRS mail, USB-stick sneaker-net, UUCP, modems, dialups, OTP encrypted SMS still. It's low bandwidth but important information is actually really small.
IPv4/6 may die but there are still ways of shifting stuff around that is important.
