The FCC has the right to monitor the amateur portion of the spectrum, but amateur radio is generally self-policing through organized volunteer observers and observation by the general amateur population.  The FCC has been a partner in ending the most egregious violations.
Using amateur radio for business is and always has been illegal.  Such activity avoids business licensing fees and regulations and use of public telecommunications.  Of course, using amateur radio for illegal activities such as drug smuggling, terrorist planning, and avoiding pursuing apprehension is illegal, as well.
Permitting encrypted communications will take away the communications transparency now existing and render self-policing impossible.  As the cost of spectrum increases, the pressure to use illegal communications mode will increase.  Allowing encrypted amateur radio communications would make it a natural option for illegal expansion of business communications.
Furthermore, combining encrypted communications with broadband data transmissions makes the temptation greater, and at the same time wreaks havoc with the limited bandwidth in the amateur spectrum.  Amateur radio has traditionally made maximum use of narrow band operations in its limited spectrum.  Broadband data operations will interfere with use of narrow band operations and undo much of the good that the advances in narrowband transmissions have done.
Allowing broadband data transmissions which are undecipherable by commonly available means encourages illegal operations places national security at risk, weakens the legal business services and is harmful to the amateur radio service. For this reason, I support RM-11831
