It seems like he's promoting the wrong aspect of blockchain here; the benefit is immutability. The fact that you can't `npm unpublish` from the blockchain does fit the use case. But you don't need blockchain for immutability, you just need it for trustlessness. And I think in general people don't care about trustlessness enough to deal with the overhead that blockchain requires. Plus the perverse incentives that I imagine will result from having a currency that you need to buy/spend in order to publish your packages.
