> When someone steals my debit card and spends all my cash, I dispute it.

You gave them your PIN too? Yes, then you have something you explain.

Without it no one is spending anything beyond the tap to pay amount which would typically be low amount (double digits)

Not all debit transactions require PIN inputs here in the US. Many can also just go through the credit card networks. For example, all my debit cards in my wallet right now have a VISA logo on them and can run through as if charging a VISA card. I've had other accounts and banks in the past which went through the Mastercard network. However, I do not get any of the extra protections, the money comes straight out of my checking accounts.

On top of that, I can use the card online using the same kind of credit card numbers. This does not require a PIN.

So that's the worst of both worlds.

Still a cc company involved, so they'll take a cut without any of the advantages. Not even sure why that's a product

So now I hope you can better see why it doesn't really make sense to always use a debit card here in the US. There are still interchange fees, things can still be processed as swipe + signature or just the numbers printed on the card, and you risk your own money whenever its spent fraudulently.

While there are still some interchange fees involved, its less than the overall fee with actual credit cards. Its often more like 0.5% + $0.21, the max allowable fee under the Durbin Amendment.
