But I think, these are technicalities, not a fundamental issue.
It is fundamental -not technicalities. Read my op. And try to get it this time.
This is certainly true, but in practice, this process can be expected to be rough, not smooth, and will create a lot of adaptation issues, for which we (Bitcoin users community) don't have a working solution to deploy.
So "you" (Bitcoin user's community) don't have a solution? Really? What if "we" have? - but don't want to deploy it, because that would turn bitcoin into a currency instead of a commodity, and vaporize our get-rich-scheeme.
