This is like saying “All the “sugar-sweetened beverages are bad for you” people will sooner or later realize it is imperative to drink liquids”. It is perfectly congruent to believe trustless systems are important and that the way the blockchain works is more harmful than positive.
Additionally, the claim is that cryptocurrencies are used like that. Blockchains by themselves have a different set of issues and criticisms.
I've met and worked with many people who never shilled a coin in their whole life and were treated as criminals for merely proposing any type of application on Ethereum.
I got tired of having people yelling online about how "we are burning the planet" and who refused to understand that proof of stake made energy consumption negligible.
To this day, I have my Mastodon instance on some extreme blocklist because "admin is a crypto shill" and their main evidence was some discussion I was having to use ENS as an alternative to webfinger so that people could own their identity without relying on domain providers.
The goalposts keep moving. The critics will keep finding reasons and workarounds. Lots of useful idiots will keep doubling down on the idea that some holy government will show up and enact perfect regulation, even though it's the institutions themselves who are the most corrupt and taking away their freedoms.
The open, anonymous web is on the verge of extinction. We no longer can keep ignoring externalities. We will need to start designing our systems in a way where everyone will need to either pay or have some form of social proof for accessing remote services. And while this does not require any type of block chains or cryptocurrency, we certainly will need to start showing some respect to all the people who were working on them and have learned a thing or two about these problems.
