As long as there are other people contributing, why should I do it? And if there is no other people contributing, then why to hold Monero?
That's exactly the argument why I thought it would have been a good idea to fund marketing and development from the block rewards, not from the pockets of bagholders.
I think Darkcoin has that sort of approach and I consider it good for long haul not to be dependent on the generosity of bagholders.
Actually i like that aspect of dash, it's pretty clever. XMR seams to be doing fine with donations only but it's not really a good system due to the "tragedy of the commons", your individual donation is unlikely to do much real difference.
Also i am against controversial hardforks, stuff like that should be decided from the start.
