If there is no electricity and no access to the internet, and this just happens one day without any warning, people will think less of Bitcoin and any digital currency at that point in time. They will focus more on how they are alive, how to survive, and how to adapt to that new system, which they are not used to. They will definitely not wake up from anything; rather, some will not be able to survive that situation.
No, it is not the same. There are ways to use Bitcoin without the public grid or internet, but there is no way to use a bank without that. Do some reading.
That is the big war. Bitcoin did a very rare thing by being heavily distributed before banks got a chance to take too much ownership of it. Now it will be interesting to see if they try to take as much ownership as they can of Bitcoin and absorb the market, or if they will always be chasing Bitcoin's innovative tail. It depends how much private wealth can be deployed and if people are willing to sell enough Bitcoin to make power centralization a concern. Right now, with coinbase, microstrategy, blackrock, fidelity and others with a combined ownership of 10-15%+ of the entire bitcoin supply, it is an interesting and pivotal peroid we are in regarding this war.
No, owning Bitcoin does not provide any power over it and because of that there is no war. Normal people have had a lot of time to acquire it at low prices, it is only natural that the time had to have eventually ran out. To make your post even worse, all the entities that you listed hold Bitcoin for a large number of people. There isn't really a single entity that owns a lot of Bitcoin for itself.
