When filing for a patent or copyright, say “I believe this is worth $1m” — so you pay a $20k tax on filing/renewing it. If you’re not confident that your idea can actually redeem 2% of that stated value, then maybe it’s too risky to actually be worth that much. So you say it’s worth $100k because you can definitely make at least $2k from it.
But if you’re really only confident in making $2k from your idea, and someone else is allowed to “buy license to use your material” at $100k, you’d be absolutely floored to make so much money from that idea. So if you end up being wildly successful, you’ve still made a lot of money (and can keep using your idea), but now competition/reuse is allowed past your stated value threshold.
As a society, we want land put to valuable use. We don't want a piece of super valuable land (could be producing food, etc) that is dormant simply because someone refuses to sell.
But we also don't want to be the arbiter of what counts as valuable. So you state the value of the land and pay the tax on that value. If someone else can extract more value, they can buy it from you at the stated price.
I think this sort of tax makes less sense for intellectual property, because unlike land many people can use the same idea at once.
Not just directly (e.g. costs to grant patents, hear court cases etc.) but indirectly - people can make things completely on their own and end up being sued for it because of an obscure patent violation. This has a chilling effect on innovation in general.
Because of this, making the person with the special right have to pay for the costs of that right seems fair.
However, concentration of valuable IP in the hands of the few is also a problem. Limited duration copyright provides the greatest benefit to individual authors (by maximizing their bargaining power while limiting the bargaining power of IP-hoarders through erosion) and the public domain.
I can’t see how that would work now that the data is digitised and the filings are completely automated. At best it might work for some older music, but it wouldn’t work for anything produced after the rule was introduced because services would be created to automatically do the filing for artists.
An immeasurable treasure of music and other works of art in the public domain would still be in the hands of these rentiers on that basis.
You used to need to file a copy with the Library of Congress to obtain copyright. Then they'd start filing it, but immediately taking it out on loan, and lose it. Then they'd "file" it and take it out on loan before ever giving it over; the copy for the library never existed. Then they decided to just give up on the farce, and not make you file.
To renew a work, you should have to actually file a (non-DRM) copy with the Library of Congress, and not take it out on loan. If it's important enough to renew, it's important enough for the Library to demand an actual copy.
Now, I don't support having to file with the Library of Congress for the initial copyright, that'd disproportionately hurt independent people who publish on the Internet.
