The big unknown is how long your need will last. So, by your definition, a "profiteer" is anyone who has more than they need when "it" is all over. But the question again is, how long will "it" last?
If you prepare to be self sufficient for 60 days and the calamity lasts 20, and there are those who did not prepare at all, are you still a profiteer? I think not.

Stock up to the point you feel safe and or comfortable, share what you can with those you choose to, and watch your back.
