I’m unsure what you mean by “no chargebacks” - chargebacks are provide the consumer recourse in the event of a dispute.
And it’s a core motivation for cryptocurrency, in the original Satoshi paper.
This is a microcosm of most of my issues with crypto discussions. In a (quite naive) vacuum, the arguments sound great. If you wanted to run Earth 2.0 with crypto, have at it. It doesn't fit in alongside the existing systems and, by the time it becomes "the main system", you can be certain that those in power have modified it to have the same issues as the original system we all hated.
