What if I say, "it's not worth $1T to me but I'm doing it for the memes"
Are you selling me just the apple?

Whether someone else will share your judgment of its worth is highly unlikely, but it is also entirely irrelevant. Worth has never meant "objective value to literally everyone."
I think your definition of value / worth should be based on the seller, not the buyer.
There are contracts that involve exchanging $1 to satisfy some legal requirement of consideration, but the relationship created is worth much more than $1. And of course there are barter transactions where items are exchanged directly without any specific valuation in money involved at all.
