LIke the title says.................
The title directly implies that it has at least some similarities with sidechains, which it doesn't. If you're trying to say that it does not, then applying the word 'sidechain' is redundant.
Even though your suggestion has potential, was not one of the points of Bitcoin to get rid of 3rd party control (e.g. banks, companies, etc.)? I don't think I'd like Visa handling my money nor being able to see what I do with it. Your suggestion does seem a lot like a Bitcoin debit card; what would be the difference between those cards and your suggestion?
That's prolly what I should call it, Bitcoin Visa card or app.. hum.. yes more accurate.

Well you still have the opition with bitcoin. Sure you can use cash in person with the current banking system but online the only way to send money without getting appoved by the banks is crypto.
I guess I see you're point though. Bitcoin should be ready to go and ready for use without having to get a third party involved.
