The main thing is that blockchain can hardly fit within the corporate mindset who works in a pyramidale manner. And most buisness cant really operate smoothly without trust and accountability. Hence why you see an amount of scams and lies unprecedented in any industry.

And immutability is not always a good thing, can see the original dao fiasco as an example of this.

Now there are also advantages, and i cannot help but to see original bitcoin design was a centralised design if you follow satoshi words.

The problem i think is that it has be sold under false premise to a lot of guilible people with feeble understanding of technical and financial issues, in schemes that actually involved trust without provable trustwothyness.
