Although the monetary value of Altcoins, currently and for the most part, rely on the value of Bitcoin, they are not necessarily mutually exclusive. Once more fiat to altcoin pairings start to get introduced, I think you'll see that reliance and correlation dwindle somewhat. And the reality is, while Bitcoin serves as a great store of value and is more widely accepted as a form of currency, so many altcoins are not even attemtping to compete in that space. If anything, Bitcoin can only be truly appreciated when it's in the midst of all these altcoins because, the truth is, we always need a point of comparison to recognize something's worth and value. Nothing operates in a vacuum, and this holds true in crypto as it does with anything else.
