At least in Germany, but I think in most countries, there are regulations that add some cost to CDs, DVDs or video and audio cassettes that is used to pay off the potential of people multiplying and sharing copyrighted work, be it by recording TV or burning a CD copy for a friend.
An approach for dealing with copyright in the future might be to extend this, too. In Germany, I think this is sometimes to refered as a "culture flatrate".
Everyone pays a monthly or yearly fee that is used to pay off IP creators, and everyone can freely share. Of course, the challenges are ensuring that there is a fair way to determine how to split the money, and that the fee is large enough to cover all the IP creators. So it might remain problematic, but I am not that familiar with the specific suggestions. I think there are still concepts for paying for individual products - like a CD in a music shop. And some say it would just be a supplementary system and live a fringe life.
I generally thing that subscription based services to _access_ downloads might be the way of the future for digital media. You pay a fee each months and can download X media titles per month. One you downloaded them, they are yours. Maybe if you somehow lose them, you can get them back even if you no longer pay for the service (or you repay for the service and already downloaded packages do not count against your limits).
The challenge of every approach is to balance the chance for the creators of IP to get payed for their work and the interests of the customer for easy access.
Especially since probably both customer and the IP creators want too much for themselves.
