Yeah, the whole "you can't have any money, and you also can't leave the country" bit... like just imprison him at that point? How is this in any way meaningfully different from just jailing political dissidents?
Even then, prisoners are at least supposed to be fed by the state (albeit not to a necessarily high standard...), this guy literally has to submit a document to gain permission to buy food?! (https://xcancel.com/hussedogru/status/1925845756927197233)
He has a lawyer who will appeal the decision (and is presumably working pro bono, given that Hüseyin cannot access or receive any money to pay anyone with...) and is planning on suing the European Commission - but there is no clear timeframe on a response by the Commission (see from this timestamp: https://www.youtube.com/live/MZ0l78jIg3U?t=1711).
So I guess theoretically they could just drag this out for years - and, given that he's legally forbidden from holding a job and earning any more money than what he had at the start of the sanctions, and anyone sending him money or food could also be sanctioned... he and his family would eventually just straight up starve to death? Like I genuinely still can't grasp the absolute insanity of the way these sanctions work, we're not talking about some corporate entity here, this is one guy who's just... not allowed to have money anymore?!
