Wow, this post hit just too close to me.
I came to same conclusion quite a while back (the author also mentions that we most probably always know this); BUT never able to get out of that mindset.
I think fixing boundary issues is a hard problem, but still solvable. Dealing with Your Things (or atleast the ones you think are yours), i.e stuff that you have marked as your boundary, seems much much harder to deal with.
My mind has argued, and won to some extent, the opposite, but within a boundary: if you are responsible, why not do it better, if you are not doing it better, what is the point of it all?
