it can only support a deflationary monetary system, no inflationary ones and so is useless as a trading currency
it has no native fungibility maintenance
governance is by contention only, which has already lead to forks in the community as well as the chain itself
it's one of the most centralised assets in the financial universe with 98% of the supply being held by less than 0.1% of the world population
it's slow at confirmation (a good thing IMO, but if you're trying to top up your credit card when the shop's closing in 10 minutes, forget it)
the Lightning network will not fix this as it only works for off-chain transactions plus...

Your criticisms are all the strengths of the current fiat digital monetary system. Enjoy, you have it today.
