You are only proving my point.
The reason I bring up ATR is because it actually fixes a massive portion of the economic model of blockchain that makes it inefficient and unsustainable.
You can cast the pejorative "buzzword" on anything - what do you expect, new solutions won't get new names? At some point you have to dig a little deeper than the fact that something has a name you haven't heard of before.
Anyways, and to your point: blockchain can't be expected to survive if the people who get paid for running it add zero value back into it. We say we are paying security, and we are, but that simply isn't good enough. If you can't pay security out of the same funds as infrastructure, then the infrastructure fails without central intervention and your objective security cost is pointless because you can find equivalent vectors on the monopolized infrastructure.
ATR takes money that used to go towards hoarding wealth or crunching numbers and forces nodes to hold data - all data, that should be on chain. It solves the problem you are keen to point out - that infrastructure will collapse even if the chain promotes itself as permanent. ATR gives you economic guarantees of what is only ideological in current chains.
If you're not too sensitive to new terms, look into Saito. It solves the other problems of sustainability and infrastructure centralization (as an attack and monopolization vector -- not to mention scale bottleneck).
