Effort is inversely proportional to popularity. If something is effortless and serves a need, it will become popular. Bitcoin was basically effortless to operate in the early days.
I don't think it should be up to users to carefully collect works that they want to "make decentralized". Decentralization should be the norm.
And it shouldn't be up to them to worry about the legal ramifications of doing so. The network itself should ensure anonymity, like Tor.
Currently there is no such technology. IPFS came close, but it fails the anonymity requirement.
