Fallacious proof/Bread

From AoPSWiki

This explanation is incomplete. You can help us out by completing it.
As you see the nothings described in the proof are not the same nothings. The fact that nothing is better then happiness and success is the same as saying it is better then anything else in the world. Crumbs of bread are better then nothing says that having bread is better then not having bread. This nothing is quantitative while the other nothing is only an idea.
