So you understand the concept and need for self defense. Pepper spray and tasers don’t always work. If your assailant is on mind altering substances, pain compliance tools like PS will be inaffective. Tasers won’t work (or are less likely to work) on winter clothing.
If you’re cool with your odds that’s fine, but I’m not willing to risk my life (or more importantly my partner’s life) when conceal carry is just as physical easy as PS.
