That's a funny straw man used against libertarians: that a person's only desire in life should be the accumulation of resources. I've never heard anyone argue that.
Aside from those who derive pleasure from their work, what desires can be fulfilled without the accumulation of resources?
Also painting/drawing, writing music or books, writing software/apps, blogging, cooking, racing cars, taking photos, traveling and writing guides, and having sex. All activities that people derive pleasure from that others happily pay them to help them continue to derive pleasure from it.
