The USMC thinks it relevant. It's the only fighter they have that can take off from the LHAs & LHDs, & the USMC cares about that. I keep reading how (just like the UK) they're worried about how to keep enough Harriers operational until F-35B can replace them, because their Harriers are piling up hard hours, & still have to last a good few years. F-35Bs aren't suddenly going to appear in large numbers: they'll trickle in gradually to start with, & won't be fully operational for a while after significant numbers have been delivered.
Don't expect many sound Harriers to be for sale, ever. Retired ones will be stripped for parts while there are still Harriers in service.
