If you're just some nobody representing yourself instead of an expensive lawyer acting on behalf of a large company, maybe the judge will even try to be extra nice when he explains why the argument doesn't hold water.
The thing everybody ignores about this is context.
Suppose you upload a copy of a work to someone else over the internet for <specific reason>. Is it fair use? That has to depend on the reason, doesn't it? Aren't there going to be some reasons for which the answer is yes?
The "problem" here is that the reason typically belongs to the person downloading it. Suppose you're willing to upload a copy to anyone who has a bona fide legitimate fair use reason. Someone comes along, tells you that they have such a reason and you upload a copy to them. If they actually did, did you do anything wrong? What did you do that you shouldn't have done? How is this legitimate fair use copy supposed to be made if not like this?
But then suppose that they lied to you and had some different purpose that wasn't fair use. Is it you or them who has done something wrong? From your perspective the two cases are indistinguishable, so then doesn't it have to be them? On top of that, they're the one actually making the copy -- it gets written to persistent storage on their device, not yours.
It seems like the only reason people want to argue that it's the uploader and not the non-fair-use downloader who is doing something wrong is some combination of "downloading is harder to detect" and that then the downloader who actually had a fair use purpose would be able to present it and the plaintiffs don't like that because it's not compatible with their scattershot enforcement methods.
Well there's also the issue of enablement. If you're overly enthusiastic to turn a blind eye to illegal conduct you end up being labeled an accomplice. But of course that would seem to apply to Facebook here in equal measure.
[0] I don't like to say "represent yourself." I once angered a judge by pointing out that you can't "represent yourself, you are yourself."
With a guilty plea. They don’t walk away without a conviction.
Property law is mostly concerned with protecting the rich from the poor, so when a rich person violates the property of a poor person, the courts can't allow the inversion of purpose and will create something called a "legal fiction," which is basically the kind of bending-over-backwards that my children do to try to claim that they didn't break the rules, actually, and if you look at it in a certain way they were actually following the rules, actually.
Value is not set by what you put into it, it is set by what people are willing to pay for it.
Browsing in a thrift store can be very enlightening!
Is a human life literally worthless, because they never pay to be born?
The map is not the territory, the price is not the value.
Less facetiously, you're committing a semantic error.
What value something has is totally dependent on who is valuing it.
More formally, it's the Law of Supply and Demand.
What do you base that belief upon?
Many judges take a dim view of expensive lawyers trying to pull the wool over their eyes with sophisticated but fallacious arguments. You have to deal with a lot of BS to be a long-standing judge, so it seems like resistance to BS may be selected for among judges.
