I'm saying: I can imagine ways of running a political economy other than capitalism, and I know of other people who have done more work than I have to imagine such things, but there just doesn't seem to be very much interest in an authentically post-capitalist system relative to the vast interest in taking some other political issue entirely (technology, the environment, race, gender, various national or inter-imperial rivalries, etc) and conflating it with capitalism to encourage pouring a lot of effort into it (the thing conflated with capitalism).
