Not a silly question. As long as we follow FCC rules and licensing rules, GMRS users are pretty wide open to use the band as they see fit.
Whether it's communicating while doing activates, talking to immediate family members or treating it like a hobby and experimenting with equipment as the rules allow the FCC doesn't care how you use it. As long as they get their 35 bucks.
Now, if you break the rules through experimentation, start advocating to turn GMRS into HAM or try to dictate how other licensees use GMRS, expect immediate and less than positive feedback.
And, rightfully so, will be directed to HAM radio where tons of people make it a hobby.
Enjoy!
