Isnt dating just a more expensive version of a hooker, less risky?

Think about it men have to pay for the dates. By the time you actually get any you would have payed atleast twice as much as just going to a hooker in the first place. You know what your in for whereas With dating you could get rejected, lose self esteem but with the hooker a guaranteed dose of serotonin(happy hormones after sex) released into your brain once every couple of months.
