This is a chicken and egg fallacy. You can't tell what would or would not be made in the absence of an incentive that has never not been provided.
> Would you rather they didn't have the option which would result in the effort not being expended to generate such information?
Yes, I would argue absolutely that valuable information would still be made because those that would benefit just from the information existing - not from the potential sale of said information - would still fund its creation. Someone that wants a painting will still pay for it if or if not they can sell the finished work. The think tank researching a cure for cancer will still have ample funding sources from those who think not having cancer would be beneficial regardless of those sponsors ability to profit off said cure.
> I don't understand how someone can argue that it is unfair that they have an option to do so if they choose.
Its largely a problem because its both default and implied. Its in the same class of problem as if the government tried to restrict air - you had to pay to breathe and are charged per-month. Despite the air being "free" and "everywhere". Its a tough analogy to write though, because there is no true analog to the modern miracle of information propagation being infinite and endless - we truly have nothing else worth so little as a copy of a number to compare it to.
But fundamentally its having your cake and eating it too - if you want to monetize your creations, you make them for free (at expense to yourself) to try to monetize something that has no value (copies of it). Its so abjectly opposed to reality and true scarcity that subconsciously drive people to feel no serious shame in piracy despite them "stealing theoretical profits from the rightsholder". But thats really all you are taking. In another light, a random stranger is offering you something for free and without recompense that they have, just because its so cheap to store, transmit, and replicate. That is magical. We take this modern miracle of technology and bind it in chains to try to perpetuate a model of profit that doesn't make any actual sense in actual reality given the scarce inputs (creative capability, motivation, and efforts) and infinite outputs (information) involved.
