I don't want "peace of mind". I (a Canadian) want to be able to buy something online from a US supplier and have it shipped to me in Thailand. This is just not possible with any kind of chargeback-enabling payment method.
Just because you haven't been in a situation where the "fraud protection" is impacting your life (or your sales) doesn't mean those situations don't come up for others.
I don't know which debit cards you're referring to but I'm almost 100% sure that the cardholders are not liable for fraud. Meaning someone else along the chain is liable and is monitoring/blocking transactions to reduce that liability.
WTF are you saying?
Something more comparable to Bitcoin than regular banking would be Western Union; they make 5 billion dollars a year in revenue transferring money. And they charge vastly higher rates than the Bitcoin network does, charging in the 5-10% range for for transactions, which is a pretty hefty overhead.
So does anyone else with access to your information. How sure are you that your account info is absolutely secure enough to prevent that AND will remain so for the lifetime of your use of a specific cryptocurrency?
I'm not, and it's irrelevant because I only have a tiny fraction of my net worth in easily-accessible Bitcoin at any given time.
I'm not advocating replacing bank accounts with Bitcoin, I'm just showing that Bitcoin does solve real problems that traditional payment processors cannot or will not solve.
