Sure, the point is that either way (either by compulsively buying things, or needing to purge down to the absolute bare necessities) you're allowing consumer goods to control you. Those of us who don't feel consumed by goods would gain nothing by purging of everything. I own all the things that the OP purged off in his need to cleanse, but, none of those ever get in the way of me going out.
My point is simply this: I read things like this all the time, and it makes me very happy that I don't feel compelled to control my belongings to be able to live a happy life.
