The point of the meme is: If you don't know where your own boundaries are, you can't expect others to know where your boundaries are, either.
Boundaries are not universal, they (along with values) vary from culture to culture and person to person.
And when people do cross the boundaries of others, that doesn't necessarily mean they're trying to take advantage of anyone - more often than not, they simply have poorly-defined boundaries, themselves.

Not to sound trite or circular, but wouldn’t they have to see them in order to know to cross them, to take advantage of you?
