I don’t think it’s even that fine a line. Don’t exclude people actively. If you want to talk to your rich friends about EA first, that makes sense, but there should be virtually no reason to keep someone out.
(If it does make sense to exclude people actively it might make sense to use a vehicle that society has decided is acceptable for this—for example, it’s considered relatively acceptable for a university to reject a student applying to it, a business or organization to reject someone applying for a job, etc.)
