Not arguing the toss... some people are used to waiting too! But you asked why people make such a big deal about instant payouts... and certainly
there is no good reason why people wouldn't prefer instant gratification! 
Nash - nice one. Can't say I like that feature...
Now, isn't this the very reason that casinos cite as to why it is simply impossible for them to verify ID before accepting the deposit - they MUST offer "instant gratification" else the player goes elsewhere that does.
When the CASINO has the money, suddenly this "instant gratification" is no longer an issue, they even claim players WANT a pending period, and have complainrd vigourously when they find the "pesky casino" has gone and paid them instantly (yes, said to me, by a casino when I queried the reinstatement of a pending period after they experimented with instant processing).
When a player has been paid, THEY have control of the money. This does NOT affect their ability to enforce their own "wait", perhaps by removing it from where it is via cheque or wire to their bank, BUT it gives them the choice to take up offers at other casinos they are members of, and not suffer the irritation of seeing an offer expire because another casino has held on to their winnings for several days.
It's bad enough with these new rules that payment must go back to credit cards, they may flush & process instantly, but my card company keeps me waiting 3 days. Worse, I CANNOT spend the money as I choose, I can only PURCHASE things with it - it is almost like paying my win in, say, Argos gift vouchers, instead of proper money.
Take as an example my win at Prime (10K). The deposits were 400 from a card, followed by 300 from Neteller, but the ENTIRE 10K had to go back to the card. I got paid, although I had to wait 3 days to be able to use the money. The problem is that I am restricted in how I can spend it. I CANNOT pay bills with it, but only buy things from merchants that accept credit cards. I CANNOT put 3600 into a cash ISA should I wish, nor can I pay off my other shopping credit card from the winnings. Pretty much the only thing I can do is use it as gambling funds. Payment to Neteller would have allowed me to have the money as "proper money" right away.
There is no reason why, once a player has passed ID checks, that payment cannot be made instantly, and to the method of receipt most convenient to the player. Casinos seem to pretend that nebulous "international laws" make them have to pay in all these strange ways, different at each casino, and have these compulsory delays.
There is one casino that says the 24 hour pending period is "for security reasons" in the confirmation email sent upon a withdrawal request.
I will TOLERATE these waits - I have no choice really, but this DOES NOT MEAN I AM HAPPY WITH THEM.
