In which case, how do you propose they are developed? It's like taking copyright protection from artists without the artists' benefit of having enough of an individual personality and connection to the customers that they could viably depend on the customer goodwill.
Isn't copyright law more about protecting the interests of sleazy record producers?
Perhaps, but that's sorta the point - an artist could get by on the customer goodwill - not every one all the time. Suppliers of basically industrial raw resources such as agricultural biotech companies equally depend on the copyright law as status quo - but unlike the former, they don't really have an alternative if they lose it.
Even still, if it were about protecting record producers, it's only a non-issue nowadays, where a musician may reliably craft and disseminate their work online, using readily accessible, if sometimes specialist, software - but that's only the case thanks to home computing and the Internet - if you would remove copyright laws a hundred (random number, less would probably work better) years ago, you'd get roughly the same situation as Biotech is in nowadays.
Either you'd protect the producers, sleazy as they may be, or you would harm
everyone by putting the only people with the infrastructure to meet the needs of secondary producers - musicians in this case - out of business, either until the remaining surviving producers are even more of a monopoly or until *nobody* can release a LP because there is nobody able to handle it.
