On the SAFE network it will be difficult to defend copyrights and patents and so on. Is that bad? Yes, for how society works today it can be.
In the future however automation will more and more replace the need for human labour. This means that money can gradually be made obsolete. And without money, the need for copyright, patents and even for contracts starts to fade.
This means that money, even cryptocurrencies, are merely training wheels for primitive civilisations like our own at the moment. The same with calendar time which is useful yet should be optional, just like money. So in order to make the SAFE network work from a practical and long-term perspective the cost of storage needs to approach zero. And that is what will happen! Because as Ray Kurzweil has said, the price/performance of information technology doubles every year (and even the doubling becomes shorter and shorter).
Will then people continue to farm in the future if they earn less and less? Probably not. However even computing resources will start to become automated and free, and hopefully not turn into a Terminator Skynet. This means that in the future machines will run farms on the SAFE networks.
