The problem with crypto coins is some have bought in and thus are vested making balanced discussion impossible. We see even with something as trivial as choice of programming language some can become very religious in their support. When money becomes involved expecting rational discussion is perhaps naive.
Money is a social construct that needs societal consent and a framework to manage it that is accountable to the societies rules and regulations. So a random person can't just create money or value out of thin air. There is no value being created here.
They can make a private coin, and convince others to use it between themselves, there were and still exist many such private arrangements in traditional economies, but the value only exists for those who choose to trust this system, and can never hope to replace the main economic currency.
Bitcoin and other coins exists in this space of a private coin based on mutual trust and of no real value to the main economy. Holders of such coins would of course love for it to become a real currency and continue making outlandishly self serving arguments about the economy so they can gain something out of nothing. But that begins to resemble a pyramid scheme powered exclusively by greed and self interest to the exclusion of that society's interests.
Not only is it a social construct, but the concept of money took thousands of years to evolve, with fits and starts, to what it is today. No matter what, some new technology isn't going to just show up all of a sudden and completely revolutionize what is an intrinsic component of human civilization. To think otherwise is to be taken in by scammers.
I know that current money systems have flaws and are manipulated by the elites. Crypto won't end up being any different in that regard, however. Inflation is a tactic utilized within the current flawed system to move wealth to the top without your bank balance displaying the change. Cryptos will end up having their own flaws to be exploited.
I think you're underestimating the impact of a durable and formal consensus mechanism that can be run by machines and can operate efficiently at a global scale by utilising telecommunication networks. This is orders of magnitude more efficient than traditional governing structures and will displace several core industries over the next few decades in my opinion.
