Re: Assuming that Government wake's up and crack down mining across the Globe.
That means if the governments like I read above a scenario tha stop meaning forever or put out countries of big mining farms the difficult re-adjusting can take in a worse scenario months as not weeks. All those are scenarios, even if it happens developers can solve it, you should not worry.
Also make your thoughts the affect of such of scenarios can be, no newly coins mint, no transactions confirmations, a frozen blockchain. But don’t worry.

If mining tops completely there will be no adjustment, none whatsoever without a single miner out there mining there won't be a new block and obviously, no way to adjust the difficulty, of course, that's impossible but in such a scenario that's what's going to happen, a frozen chain with no blocks no confirmation no way to move coins.
Let me add that Bitcoin in a worsted scenario can work without internet, that’s say don’t worry. 
In the worst-case scenario we could make bitcoin work by manually solving hashes and sending them between mining farms and by carrier pigeons, that doesn't mean it's feasible nor that it will be the same.
As I said Bitcoin can works without internet(TCP). The chain will be frozen due to high difficulty this can be solved with a 1 line of code.
