How come the slightest typo on a flight ticket means you won’t get on the plane/admitted into the country?

Question

Even correct spelled names in the in the wrong fields won’t do, like first name in surname and vice versa. Where does the problem occur? Cause you have like atleast 5 – 10 customs agents and flight staff manually watching your passport/ticket, and they should be able to conclude that the ticket is yours. Or?

In general this isn’t a problem. I’ve had misspellings, even a shortened *version of* my first name (Kenneth -> Ken) on flight tickets. It’s not an issue and in general customs and immigration don’t care about the name on your ticket, just the name on your passport.
