Here is the simple reason. It is better to team up with or employ someone with the license then to hold it yourself. There are lots of legal obligations and other issues that trigger when you are a licensed agent. Not that you are trying to do anything illegal, but simple mistakes become much bigger issues when you are licensed. Also, when licensed you have a ton of disclosure rules you must follow and missing one can be a major issue, so better to employ someone or team up with them than to be licensed yourself.

I do agree in reference to fees from brokers etc, but if you do some deals you will find someone you can work with and honestly at that point they'll work with you on the fees and you won't care as much either because they'll take the liability so their fees are fair.
