What you say is true to a point- but if you take your logic to an extreme- If you double rebuy, go all in, lose, repeat x 8 (with maybe a win in there somewhere that later gets eaten up by a loss) and take the add on, you've got 17 buy-ins and maybe only 5k in chips- not a good enough chance to last long enough to make up for all those buy ins.
