They do have EUV machines, albeit unreliable. Like you yourself mentioned the yields are the problem here. This is really more of an engineering problem, you need more cycles for quality and reliability. But it's not something unsurmountable. Intel had no reason to try hard enough, Intel is never going to get sanctioned. 'Necessity is the mother of all innovation' might come to play here. If it comes down to living vs dying, people go to no ends to make things happen.
