Yes, but I'm not arguing that, my point was for portability so it can be carried with you (or your SO) daily. A can of bear spray is pretty big to carry around, at least for most women who are on the smaller side. Nothing wrong with carrying it while hiking or camping and at home to use in case of a home invasion.
A small canister of pepper spray can easily fit into someone's pocket for concealment. Bear spray canisters are big because the propellant needs to reach like 20+ feet away. If I gave my girlfriend a can of bear spray, she'd never take it with her.
