I agree with ThePrincess; the true (RL) owner of the CDS sims should be an organization, not an individual.
If something were to happen to the current RL owner, what would the CDS do? If an organization owned the CDS sims, the leaders could change, but the organization would continue to exist.
Perhaps even more importantly, the CDS is currently beholden to the RL individual who owns the sims, which is fundamentally non-democratic. That individual may be fair-minded 99% of the time, but alas, we're all human. That's why real democracies have systems of checks and balances, so no one individual can have too much power.
There is also an issue of liability. As it stands, the individual who owns the sims bears the burden of liability associated with being a sim owner.
Lastly, there is an issue of taxation. As it stands, the individual who owns the sims must pay personal income tax on any profits earned due to their ownership of the CDS sims. That is clearly not fair - the tax burden should be shared by the community as a whole, not by an individual.
I think there needs to be some discussion about what kind of organization would be best. It's not clear to me whether the CDS would qualify for IRS 501(c)(3) nonprofit status, as such organizations must have a clear charitable, religious, educational, scientific, or literary purpose. What organizational status to RL cities have?
