I'm all for putting a lower limit on copyright, such that it expires regardless of upkeep. I'm a big fan of video game mods. Some companies encourage it, others send cease and desist letters. We can talk hypotheticals, and we can talk how we wish it worked, but we don't live in the hypothetical world, we live in a world where there are legal ramifications that already exist, even if we find them to be unjust. There are many countries with varying degrees of more or less control on intellectual property than the US. We've mentioned Japan multiple times. Somalia (with almost no functional government) doesn't even recognize property rights really (because they are only enforced at gunpoint by yourself or your community).
We can argue endlessly about whether intellectual property can even be a thing. Is all work derivative? Before countries and complicated laws, you and your buddies would just go and beat, possibly murder, the person who's encroaching on your territory, as happens in lawless areas of the world today. Most laws merely exist to prevent violent outcomes of disputes. Back in the good old days, companies had private spies and espionage/counterespionage programs to keep their trade secrets. My actual main concern is that we have laws currently, and people are taken to court for it. Not whether those are good or bad. Just that it is the case.
All the advocation I've seen here has ammounted to "Well, I don't think the laws should be that way, so everyone should break them." Go advocate. If you're in the US, go to your local political office for your party of preference, and start trying to make this a thing. Bring it to the public forefront. People got an amendment added to the constitution to ban alcohol in one of the most alcoholic nations in the world at the time. Lets not pretend that the change would somehow be insurmountable or impossible. If you aren't in the US and your country doesn't care about copyright, host a website. Do the thing.
Until that time, however, I advocate for not puting the entire community at risk because we choose to do one of the few things that even websites like webnovel, AO3, and Fanfic.com don't allow, which is the explicit linking to funding locations on fanfiction pages themselves, which pretty much everyone everywhere else except exactly on this forum agree is where the line is crossed. Right or wrong, the law exists as it exists currently, and people can be 'unjustly' punished under it. Creators with zero revenue coming from content have still had entire websites taken down thanks to Nintendo litigation. We can hem and haw about how unfair it is. Or how 'um actually' the creators should have just stood up because it was an unfair dmca. The reality of the situation doesn't change because anyone believes it should be different.
