"The lack of ability for central banks to inflate the monetary supply."
I am not clear how this helps. If bitcoin/ether becomes the dominant currency, 2008 crisis is still possible, but the recovery is not. So it seems like it would make things worse, not better?
Countries used to go to war over gold and silver, it does not seem to be economically beneficial to have a deflationary currency.
Being deflationary isn't the problem there. Stealing gold/silver happens because they are small physical objects with objective value that can be stolen from people guarding it with enough people with guns. Stealing crypto-assets is much different and given competent security policy, seems much harder to do. These assets are not guarded in vaults by people, but in computers by strong access controls and encryption algorithms.
I would, but that is a different problem, not specific to deflationary currency. It can happen whether I have dollars, gold, diamonds, crypto-assets. But with crypto-assets, being non-physical, it is possible to easily hide them and also hide who owns them, and then mafia has a very hard time figuring out who to hit with the wrench to get them.
Deflationary currency would be bad for the current inflationary system and the small group of extremely rich people, but could be good for most people, who don't want to be in debt their whole life.
