Amazon can claim it is both centralized and immutable, provided you trust Amazon.

Maybe none? I might be willing to bet that 99% of blockchains in use today could in fact just use AQLD or similar.
And this is what it comes down to: most of us live in a world where trust can, and does, have to root out somewhere. So much of our society is built around this. Blockchains feel sort of alien in this world.

No it can't. The second it is hacked and somebody alters the ledger, it is no longer immutable. Centralized security models eventually all get hacked. What you could however say is that the application you need to have immutable isn't super mission critical, and thus you can afford a very low probability - but not 0% of getting hacked.

And this is where you might be a bit out of touch. From China hacking US IP, from Banks world wide manipulating markets, gold, Libor, frequent global election fraud, government mis-spending of funds, corporate & government accounting fraud, Fukushima lies, Fakenews etc. The trust people have in institutions and governments world wide is in an accelerated decline. We are constantly asked to trust, and we are constantly let down. Properly decentralized blockchains are 'Trust machines'. They aren't alone going to solve all the issues I mentioned, but they do have the potential to increase trust in many processes related to these various issues. The key requirement is decentralization though. A blockchain managed by a single entity is nothing more than a dumbed down over-marketed database with limited use cases.
