I agree that strong or at least clear and firm boundaries are important. But to say we will end up feeling used if we have not yet developed boundaries for ourselves is victim blaming. Shouldn't people in your life-- your boss, your friends, your religious cult leaders-- simply RESPECT your autonomy as a fellow human? If you end up "feeling used" by someone (or by an entire group of someone's like SGI) then it means THEY ARE USING YOU. And yes, they are using you because you don't have strong boundaries for yourself but that is NO EXCUSE to treat someone like that! In fact, if you are an actual kind and aware person, you might notice the person has poor boundaries and therefore you treat them with caution and NOT TAKE ADVANTAGE of them, like SGI always does.
