That's a very widespread misunderstanding of the law, which doesn't even mention the word "commercial". All civil sUAS operations are regulated by Part 107 unless they qualify for the recreational exemption:
Sec. 44809. Exception for limited recreational operations of unmanned
aircraft
(a) In General.--Except as provided in subsection (e), and
notwithstanding chapter 447 of title 49, United States Code, a person
may operate a small unmanned aircraft without specific certification or
operating authority from the Federal Aviation Administration if the
operation adheres to all of the following limitations:
(1)
The aircraft is flown strictly for recreational
purposes.
As long as he has no intention of using them, for example to acquire a scholarship, maybe yes. So no - of course not.
An FAA interpretation of the exemption:
The statute requires model aircraft to be flown strictly for hobby or recreational purposes. Because the statute and its legislative history do not elaborate on the intended meaning of “hobby or recreational purposes,” we look to their ordinary meaning and also the FAA’s previous interpretations to understand the direction provided by Congress. A definition of “hobby” is a “pursuit outside one's regular occupation engaged in especially for relaxation.” Merriam-Webster Dictionary, available at www.merriam-webster.com (last accessed June 9, 2014). A definition of recreation is “refreshment of strength and spirits after work; a means of refreshment or diversion.” Id. These uses are consistent with the FAA’s 2007 policy on model aircraft in which the Agency stated model aircraft operating guidelines did not apply to “persons or companies for business purposes.” See 72 FR at 6690.
Any operation not conducted strictly for hobby or recreation purposes could not be operated under the special rule for model aircraft. Clearly, commercial operations would not be hobby or recreation flights. Likewise, flights that are in furtherance of a business, or incidental to a person’s business, would not be a hobby or recreation flight.
