When someone named adamomada comes to the bank for a loan, the presumption is that adamomada will repay the loan.

If they knew it wasn't you, they wouldn't have written the loan in the first place. They're asking you to repay it because they really do think it was you.

If "it wasn't me" was all anyone had to do to get out of paying a loan, many people would do it.

It's much more subtle, fraud is accepted and part of the business. Even if you are not 100% certain of the identity of the person, what matters is how likely you are going to get paid back.

For example, when you purchase online, some merchants do not check who is the owner of the card, or the address. It's done on purpose, because some people borrow the card of the others, some people don't want to use their card, etc. And overall it's all about risk management, but if the holder is really the one in front of you is just one factor among others.

It’s not “accepted” as much as it is just simply impossible to completely avoid at any kind of scale.

Even if online payments were eliminated, and you had to show up in person with a birth certificate and passport to perform a transaction, fraud would be non-zero.

To have a functioning business, people need to be able to use the system.
