no country has the ability to go to the moon tomorrow. if there were a pressing reason to do so, the US and probably china or russia could do it eventually, but it takes time to organize that sort of effort. it's probably true that the time between deciding to go to the moon and actually doing it would probably be longer today, but a large part of that might be increased expectations for the crew's safety. it's a similar story with the PPE. the US has moved a lot of manufacturing capacity overseas because it's economically efficient. the US is certainly wealthy enough to manufacture as much of this stuff as needed, but it isn't a switch that can be flipped overnight and the unit cost would be much higher due to regulatory burdens like worker protection.
