Being hippy, why?

Every one wants to be a hippy when young ,starting from Gautam budhha to Laotze to Osho to gen today :) Ultimately it all gets washed with age ..........why?Do not overload self with further illusions .Clear the cobweb of ugly world instead of creating a new imaginary one for yourself.The feeling of loneliness makes one eager to go astray and the origin of this feeling is ego itself.Kill the ego to feel the natural psychedelic of love and empathy.
