Isn't it possible, even likely, that at some time in the future a majority of miners would simply implement software changes to increase the amount of bitcoins generated? The incentive to do so is rather large, is it not? Thoughts?
What's the incentive? Why is it likely? I can only guess at why you would come to such conclusions. I think the opposite. I think there is great incentive against changing such a core part of the system and it would be very unlikely to change.
Maybe you conclude that miners want to just 'pay themselves' extra, but if you think about it, many people would disagree and so there would be a fork. And the diluted coin would be instantly deemed inferior due to its reduced scarcity. In turn, no miner in their right mind would waste their hashing power on it.
Don't forget, users have nearly as much power as miners have. They're the ones that are BUYING all those mined coins! If the users don't buy DiluteCoin, (and merchants don't accept it), then miners are hashing a useless coin.
