I think the biggest difference between CB licensing and GMRS licensing is that CB Licenses were on paper and the reply was on paper and had to be stored in filing cabinet$ and someone had to be paid to handle all that paper and deposit the check and follow-up on bounced checks and returned mail, etc. My GMRS license was filed digitally, paid for digitally, and sent to me digitally. All on a Sunday (i.e. no human beings involved). Bits on a server are so cheap (not zero, but really cheap) that as long as people are willing to pay for a GMRS license, they'll take the money.
