Riding brakeless on a scooter is really no different to me because its just a scooter so its not like its "super dangerous" or something. IMO riding brakeless on a scooter is just another copy of bmx.
I've rode breakless for about 3 years after my break snapped. I love it though because i ride ski and now i dont have to move my feet around as i never put them on the back wheel. Tyre taps are easy and so are manuals.
If you feel you dont need the brake for any of your tricks then take it off, otherwise if you need it leave it on. Personally i think riding looks better if you learn to do stuff without pressing a brake.
