Yes you have a point but if you some Google search for keywords "Movie License" you will find about 3 different corporations competition for top spots in the search results. When i did some more searching i discovered one of them owned several other "movie license" related domain names and are ranking them for different keywords, .com .net and .org all taken. So i have no doubt one of them will definitely be interested in my own "movielicense.com" for a decent price since i dont intend to develop the domain name.
As for SalesLicense.com there are many companies the domain can potentially be sold to because the keyword " sales license" has many related keywords and relevant companies in each respective field. For example
retail sales licenseinsurance sales license
real estate sales license
car sales license
The only thing about me is that i am kinda used to quickly reselling my domain names to other domainers and end users in some cases, because of this i usually dont have time to do extensive potential buyer research for each domain. But am sure that will change soon
