This is a weak sort of agency. Indeed I'm able to resist capitalist oppression by not working, but if the consequences are that I starve to death than I hardly see that as a reasonable outcome.

I think this is an uninteresting definitional question at this point, though. If I'm misusing agency than so is the author of this piece; the important thing is that we be able to communicate, which I think is possible. If you want to further nitpick specific words to garner karma, do it with someone else.

There are lots of other things you can do to resist capitalist oppression - e.g. Unionize, or create other kinds of social support. A strawman isn't very useful.

I'm sorry you've chosen to be accusatory instead of reasonable.
