Is self-defense training for girls a waste of time?

Anonymous
IM A WELL BUILT GUY if I wanted to assault a girl no martial art would stop me I know not all guys are built strong like me but even those average sized males would manage to subdue a girl trained in self-defense I recon pepper spray or rape alarms would be a better investment.
So I am asking is self defense a waste of time for girls?

I'm not saying its a complete waste of time sure there are benefits like the exercise or self confidence building but I think in the end of the day weapons are best
