It seems to me that a world without the internet would become a pretty apocalyptic place (at least for a while), but people would adapt as always. Of course, this would have indescribable implications for Bitcoin and anything else that depends on the internet, but I hope it will not come to that - because if something like that were to happen, it would probably be a consequence of some global natural disaster or a new world war. In that case, what will be most valuable is food, water, medicine and means of self-defense.
Apocalyptic? I think it's a bit of an exaggeration!
You remember probably that in the 90 in all of ex warsaw pact states we basically had no internet, there were 40 million users in 1995 most of them in the US, yet the world was still pretty advanced, of course, it would be bad for companies and communications but it's not going to be that damaging to civilization.
To the comfort of our life, that is a different story, no internet, no access immediately to information, no online payments, back to phone calls, going through 100 shops to find a thing you can order now with a click, it's going to be a nightmare.
But a shortage of food, no, all the farms in my region including my family's one will keep going, it will be a pain in the ass to talk with suppliers and distributes but we're back 10 years only!
Hlwever , you will still own your bitcoin without internet.
Your private key is just a number. You can still sign transactions without internet.
Let me bet on 99% of users having to google "how to sign a transaction"....
