First, there are quite a few very obvious reasons why it's in humanity's interest to regulate space missions. You want to minimise space debris, for example, because it could result in a series of collisions making near-earth orbits a wasteland you can't cross.
That's why there are rules on the size, structure, orbits, data sharing, disposal mechanisms and other features of space missions. These are set out in international agreements and enforced by the operator's country of origin. Greenland is a territory of Denmark, and your proposed "pirate launches" would be regulated by the European Space Agency. Problem (really) solved!
There's also stuff like the Outer Space Treaty, a valiant (and mostly effective) effort of international cooperation preventing a wasteful and dangerous arms race in space. Yeah, Trump seems to be reneging on that as well, go figure.
"Extremely small office" is simply a fact. There are three people working on this subject. Since most people will agree that SpaceX's videos really isn't much of a problem, nobody is actually complaining about past non-enforcement. Therefore, the lack of enforcement really isn't a very strong argument for increased funding, is it?
Providing a potentially understaffed office with the resources it needs isn't a "bribe". These people would not personally get any money. They are not asking for money from SpaceX or any other interested party.
Regarding this specific licensing requirement, a good read is https://www.nesdis.noaa.gov/CRSRA/files/15%20CFR%20Part%2096.... It's the result of a public deliberation and shows the different goals, stakeholders, and experiences underlying the regulation, and how they have to be balanced.
