That's really hard to say because I don't think developers design systems around being a complete waste of time. Whether or not the product of a craftsman is a completely useless throwaway depends on how much demand there will be on stuff they produce and how much will be readily available for sale from NPCs. Impossible to say right now. A lot of this is going to end up having to be balance tested during pre-release phases.
But they are definitely going for a 'hardcore' experience. Judge for yourself:
Economies are likely to be very localized given the difficulty of travel so that will help with the demand side of things. People in settlements will have to rely on their local tradesmen for the things they need.
Furthermore, nobody will be able to get to the pinnacle of their profession in one lifetime, so on that basis you can also get an idea of the design mindset at work here.
