So the Queen decided to punish her under the guise of exploitation of their technology. And Yuri has to come up with a dress design that doesn't exceed 3 dollars of their currency (not including labour cost) and make 500 dresses for 500 different people. She's being punished for a crime she didn't commit, for being innocent. That's not a benevolent Queen, fair enough. But good Lord, that's not a wise Queen either, sending a scary, borderline tyrannical, message.
Realistically, Yuri can take her business somewhere and start all over again. It will take some time but she won't be exploited. On top of that, the Queen would be stuck at step 1 looking for a new and innovative designer, who she probably won't find again.
But this is a isekai so I think we all know how this will play out.
