Because it's not that big of a deal. People's CC number is everywhere. In databases, on receipts, etc. It's a little more risky but so are many things people do daily like owning a Ford truck (some of the most stolen vehicles) or using ATMs.

Where I live the full no is not stored on receipts, and in dbs it must be encrypted. I think emailing CC numbers around would be breaking PCI compliance, and that would be a big deal. There's no way I'd email a CC number.
