That may be true but to use it that way legally you would need an amateur
license, and this is not just a paperwork exercise, you have to pass FCC
exams covering electronics and radio theory (plus laws and regulations) to
get one. For most people, it's not an option.

Very few people would have significnat difficulty passing the technician class
license exam that's needed to operate on 2.4GHz. Indeed, there are many
month-long (meet a couple times a week) classes and even weekend "cram"
classes that have near 100% success rates in getting people their tickets. A
passing score is 80%!
