here's something to debate that *might* help (or might just draw more ranting from the other side):
In my opinion, after the FA signing period, cash (in the form of payroll budget in excess of player salaries) does not have a whole lot of value
you can't buy any "good" FAs with it ... it is only worth 50% of what it used to be worth if you transfer it to prospects (and less than that if you didn't budget high on int'l scouting) ... you can't use it to buy down the out years of your own players (like a bonus could in the FA period)
you can use it to claim players off the wire ... although you would expect you aren't gettin 100% for the money, or the guy wouldn't have been waived
you can use it to absorb payroll in the form of talent coming to you
the one that bothers people: you can include it in a trade ... usually to bail the other side out from being short on payroll
since the cash you send actually has limited value (in my opinion based on the above), the cash you trade is "nothing" to you, but "something" to the other side ... trading nothing for something is perceived as bad for the world by some people
