With Ethereum? That seems like one of the least interesting possible use cases.

* For one, Bitcoin can do this too (though not in many places)

* For two, you can’t do it in many places

* For three, you already can buy online with paypal, prepaid debit/credit, and other checkout solutions, for less fees. You can buy a prepaid credit card useable online in any convenience store for a low fee....

I don’t think this is what OP meant.

Finally, I can purchase something without recourse in the event that I'm defrauded.

And you bought the crypto itself with magic?

You want to know how you get bitcoins without magic? Mining, trading, buyinc frik

With cash
