I understand your concern. I really don't have answer. With discussion maybe a resaonable solution could be reached. I understand the argument for and and against helmets. I feel caught inbetween. I myself will always wear a helmet. A helmet has saved my head several times.
Lately most of the motorcycle accidents in my area, a helmet did not help. The individuals suffered internal injuries due to the high impact with trucks and/or cars. They most likely also suffered severe concusions. All were wearing some type of helmet.
A skid lid will at least keep your scalp from getting scrapped off.
