Ease of maintenance if the whole car is wrapped. Don't have to worry about paint swirls from washing it and I didn't wax it for a year. Although I do wax it more than that now, I like waxing the car. I know ceramic coating... I have put over 8000 miles on my car so far and sometimes I do drive it in traffic and those little rocks don't worry me as much. But yes, if it is not worth it to you then, just don't do it. $6000 wasn't that big of a deal and I plan on keeping this car forever. In 10 years I will wrap it again.
