Since ASML builds/integrates the machine, is there any reason why they couldn’t just pull out the EUV laser from the machine, but keep the trumpf lasers, zeiss mirrors and everything else. Then China could just copy the “shooting tin droplets with a laser at 50khz” part.

Because then the Us would get Germany to ban Zeiss and Trumpf and even if they wouldn't, the whole "shoot lasers at tin droplets" bit is insanely difficult to replicate that Canon and Nikon dropped out of the EUV race.

They already have a light source[1] which they are collaborating with Imec to get ready for EUV, apparently within 2 years[2]. It will be interresting to see how far ASML will go to get around export restriction contracts, since there are billions to be made in chinese lithography. I didn’t know that the US had the capability the control who europeans companies choose to export their products to.
