I don't see the point of paying to keep it. If you are in a job or have skills which are in demand, you will be able to live and work in Europe anyway.
DH is non-EU and has lived & worked in 5 European countries in the past few years very easily. Equally I have lived & worked outside of Europe and got visas very easily.
If a young person wants to move to Europe for work, but gets put off now by the prospect of visas, I would seriously reconsider whether they are prepared enough to make the move mentally.
