I don't completely agree with this. However, I do partially see your point. Once you know something has a value it is hard to psychologically remove yourself from that. I don't think I can 100%. The fact that it can impact you in that way makes it relevant in my mind. Maybe not the way a trader would look at it but still has an impact.

Also, doesn't the value of STEEM determine your curation payout for upvotes? If the value of STEEM goes up then your upvote would have more value. That makes it relevant as well in my opinion.
