Sure, but try telling that to the IRS! Seriously (although that about the IRS is just as serious), there is plenty of ways to deconstruct the notion of self, to expose it as unsubstantiated etc. But to employ these ways leads to a neurosis, paranoia. The Western people, and some Eastern, that produced these ways to deconstruct the self are starting from the tradition of Western thought and science: it is only the truth that matters. They didn't take into account that the pursuit of truth might actually make people miserable, worse even, unable to function. Western philosophy has lived, usually, as an intellectual hobby, serious people talking about serious stuff, but not really taking it seriously. They tell you "who you really are", but they can't tell you what good it will do you to know "who you really are". They instruct you to deconstruct, but they offer no goal for that that a person concerned about their wellbeing would ever pursue.
