Because you don't think you are able to store 1000 audio CDs loss less for the rest of your life?
I mean that's not that much of space.
You probably have other similar critical things like pictures or videos so you have to have a backup strategy for that anyway.
And what music would you have which would be so unique that in the worst case scenario you are happy that you still have those 1000 music CDs but no longer your pictures etc?
Technical speaking Blockchain don't solve any real problem and it's just trending like 3D television.
There are plenty of people in the world who want to become rich. And it's just much easier to follow some hype train than putting in the real work.
The hype train also triggers people and you also might get easier fun money. But they don't understand that that fun money is much less than they actually need.
In my company the people look at Blockchain who normally already do hype topics which might or not might end actually useful in a product. But you know innovation.
Technical speaking I believe it's a problem if level: you say we have a trustproblem and need something decentralized. Now someone says Blockchain solves this Problem but they either ignore the next layer or don't understand it either. Now people think Blockchain solves the trust issue without asking how and IF Blockchain actually sol es it.
Like why would I trust an arbitrary miner somewhere and a system which is also intransparent?
Blockchain hides it's issues under complexity.
And crypto is again adding complexity. Stable coin, Bitcoin, etherium, lightning, hashing, Asics, PoW, PoS etc. And when you went through all of those words then you need to think through the implications on a geopolitical level.
And while writing all of this,.I haven't mentioned the resource issue: power consumption, co2, energy stealing etc.
Or the lyers.telling things how Bitcoin mining on unused gas is helping anyone but not asking why we even allow burning it. Or why not generating Power and forcing to build a simple Powerline or whatever.
To sum it up: there is a little bit of interesting decentralization/liberation in this topic and it might be used in weird small scenarios through the hype train bit ultimately it will take ages until something relevant will come out of it and it will look different than you think it will be.
All the garbage around the tech will leech of as other things which just won't die but they will not become the unicorn they believe they are.
