I believe he explained very well what he meant by decentralized, please stop suggesting he doesn't understand his own thoughts: it is extremely irritating.

For starters, a third party (or a recuded group of miners controlling the majority of the hashrate) can censor transactions. It doesn't matter how benevolent that party is: it can be forced to do it by the laws of its jurisdiction.

If you don't care about this, I suggest you start a new system without expensive proof of work, you can replace it with block signing (it can still be multisig). It is already coded, just fork the alpha or the blocksigning branch in elementsProject (github).
