A fundamental question

I am far from a math wiz, but I have put in some time researching Ethereum since I began buying Ether. My question is this: are the goals of eth investors and eth users diametrically opposed? As an investor, I want the price of The ether I hold to increase, thus giving my investment more value. But wouldn’t it be better for users of the blockchain if the price of ether remained static or actually decreased? Can someone explain why I am a complete smooth brain for thinking this way?
