Sell Wii u with download games and buy new ones without?

I lent my Wii you to a friend years ago, then we lost contact and I bought a new Wii u, because at that time I had a lot of download games on my old Wii U, I downloaded or downloaded them I wrote to Nintendo support that those who disconnected my Nintendo Network ID from the old Wii U console would do it at all.

For the new Wii u console, I paid 80 euro without games, now all the download games are on it again, of course. Now after a few months I got back in touch with the friend from back then and she told me that she sold my console with the games for 200 euro.

Now I have become thoughtful, is it possible that I can also sell my current Wii U with the games for € 200, then buy a new Wii U without games for € 80, write to Nintendo Support again so that I can play the games again can load on the new Wii you and then sell it again for 200 euro?

I think the whole thing is illegal, because that sounds pretty banned somewhere, but that's why this site is there, so I just ask if this is allowed or not?

This is clearly fraud and therefore of course punishable.

Okay, i already thought, thanks for the answer.
