here is my thinking:
1) I would not be giving up on certain business cards
2) as stated many of us have DW to apply for all other consumer cards so we are not really giving up on those either
3) As long as you are under 5/24 there have been may success stories with 3 or 4 BM so i am not sure why you think you would only get approved for 1-2 cards or "maybe nada"?
Look how valuable the Reserve card is and what we went through to get it. Chase has some of the best cards
2) like redbull13 said, that doesn't really help much.
3) The fact that you don't know what will be in 2 years for now negates that reasoning.
In addition, why would you leave hundreds of thousands of points, plus actual money that one can get from cards, just to wait to TRY to get a couple of chase cards ?!?
