Had an experience recently where one interface for a dapp did not work, and I was able to extract funds by switching to a different interface, and if even that had failed there were other workarounds like monkeying around with etherscan's "write contract" feature.

Decentralization and openness are amazing.

This to me sounds like a purist sense of amazement. Where because you can track the lineage of abstractions, your ability to solve a problem via many means is fun.

Future users will not find this as amazing, nor will know of other possibilities. The tourist.

future (and current) retail users may not value it very much 

a section of users holding large capital (both individual and institutions) will appreciate that there are fewer points of failure
