You're participating in airspace, and if you want to participate in airspace you have to comply with the rules for participation to not endanger others.
In ye olde times, you had to do a pilot exam, and planes and choppers were/are expensive and had to transmit ADS-B information both for air traffic security and for keeping track of abuse. If you were caught abusing your privileges, you lost your license.
Why should drones be exempt of these rules, particularly as they are mass-market things (unlike airplanes) and thus the chance of them getting abused is far higher?
