Here's what you're not getting: nobody asked about that.
You cannot say to someone who doesn't like hot dogs, e.g., "What makes hot dogs gross?" and then when someone explains why, respond, "I disagree." That makes no sense. You asked for the information, they gave it to you, so the only possible way that "I disagree" fits at that place in the conversation is if you're saying that you disagree that that's their reason. To respond "I disagree" in the sense that you don't share their taste is to fundamentally change the subject to try to have a different conversation. And it's not interesting, besides.
People have different tastes. That's expected.
Stating that you personally think it is worth the price—especially in this context, as if it's some kind of retort—is just annoying. It isn't illuminating; that you don't share the same opinion is utterly unsurprising and didn't need saying, and it provides no special insight.
