Instead of "lost coins", "destroyed coins", "the evils of deflation" your reason is "rich people buy a lot of coins"
My point is simple: these "raise the number of coins" threads become very tedious after awhile.
I and many others will/would stick to the original because we believe it is not OK to use the money system to redistribute wealth. That is what taxes are for ;)
The big difference is actually that nowhere do I personally suggest to raise the number of coins.
I speculate (and invite you to speculate as well) about the possibility that this could happen one day, and how to price in this possibility.
My question could have just as well been "How likely is it that mtgox goes bankrupt, and how will it affect the btc price?". You wouldn't accuse me of being a causal factor in mtgox's bankrupcy, would you? :P
