The only reason to hold additional Crowns is to benefit from TRs and ARs.

...or to sell it.
Anyway, I'm not going to contribute to something what is de facto your private business. Not any more.
Call it Crowns, call it Estates, but you have reserved for you more Estates that the rest of your world could possibly collect toghether.
I wouldn't contribute to such a project from the beginning, but at that time there seemed to be some decent people around who would vouch for you.
