I also had a lot of headache when a seller charged me twice and tried to send me another product because I had to charge back several transactions while explaining "yes, the FIRST one was legitimate and I got he product, but the later ones are not".

I had to charge back twice because the seller kept on charging me on the same credit card number! At least with Bitcoin you're only in for whatever you pay.

companies who fail to live up to their end of the bargin in a bitcoin world won't survive long. I've been shopping on the internet since the 90's and not once have I had to place a chargeback.. Chargebacks are mostly fraud and people wanting shit for free.. In turn goods become higher priced and that cost is passed onto all the other customers.. Anytime I have been unhappy with an internet purchase the company has always given me a refund. The need for chargebacks is truly minimal. Any company that wants to keep their customers is going to issue a refund. Companies that won't are shady and need to go out of business anyway.

>companies who fail to live up to their end of the bargin in a bitcoin world won't survive long.

Yes, just long enough, like Butterfly Labs. (Credit card purchasers: could do a chargeback. Bitcoin purchasers: SOL.)

Chargebacks and reversibility in general are essential to consumers. If shit goes wrong, it's gotta be fixable.

(This is also why nobody actually wants smart contracts. They know that the plot of Dr Strangelove is literally an irreversible smart contract going wrong. Consumers want fixability, business-to-business wants the option of lawyering out of a bad deal. The only people who want smart contracts are the businesses who currently screw over their customers with mandatory arbitration clauses.)
