IPFS afaik is a solution for storage and bandwidth as that is dispersed among the provider nodes. The problem I see is that it just pushes the problem further into the future. You temporarily solve the issue by delegating the cost but at some point xou cannot scale any further because there is no incentive for provider nodes to give you storage and bandwidth for free. That in reverse could be solved via filecoin (or a similar solution), which would allow people to pay with their storage and bandwidth (which they usually have more than they need or use), or money if they don't want to provide those.

There is no need for a shit coin to pay for bandwidth and storage. We can do that with Bitcoin using lightning or chaumian ecash.
Problems are…
- not enough users will pay for content i.e. there is not enough money coming in to cover the costs.
- whoever provides the hosting may be made legally accountable for the content.
"...or another solution"
- You don't have to pay with money, just provide some storage and bandwith. instead, that's ok too. Or perhaps. ertain clients may introduce ad based monetisation models like the way users are currently used to and just pay for the storage and bandwidth through that. The point is, nothing is free, but there are more ways than the ones that are currently most popular.
You can be legally liable in some countries but, if the authorities actually try to enforce that. they will have a tough time doing so. It took a lot to take down even the most blatant copyright violatiors like Openload, Streamango or Verystream that afaik were all centralized and thus relatively easy to target. What are the state thugs going to do, if there are millions of small scale hosts dispersed across the globe?
