He agrees with you. Hes saying that to show how what is valued and seen as virtue by capitalist mindset(saving and accumulating wealth) is actually completely meaningless and in the process of doijg that you will waste your life by not doing all those other wonderful things he listed. You could say yeah no shit but I have to make a living exactly that's the point if you didn't have to worry about it yoi could enjoy all those great things. No offense at all but if you are confused is because the fact that focusing saving and accumulating=the most importsnt thing might be a vale that is so engrained in you by current culture that it might be difficult to see it framed in a negative way. (Notice how many of the things marx puts on the list of good things aren't even super expensive consumer products which is the kind fake award given to you in return so you have the inpression that the time you spent trying to earn was worth doing it)
