Don't be ridiculous! If a company sell a membership to something, and promise certain benefits with that membership in an attempt to drive sales you can't get upset if you choose, or are unable to purchase a membership that you don't get to take advantage of those benefits.
I'll end up purchasing a Steel level membership to the well society as it's pretty much all I can afford at present, but i'm not going to start complaining when I don't get the benefits promised to the 1886 level membership.
It has nothing to do with royalty, and everything to do with the club rightfully rewarding those people who invest in the club at the start of every season.
Put simply, if you want the benefits that come along with being a season ticket holder, buy a season ticket!
