The reason the cap is large is because we are aiming to fix a global issue. We can start fixing it wirth one street or with one continent, or anything in between.

Obviously the funds required to reinvent the way real estate is transacted is well north of our cap, yet our goals are ambitions enough to do just that.

I didn't yet check your math, but it is largely irrelevant.  The reason is that we have declared from the very start that we will burn any unsold tokens. Because of this anyone who participates should benifit from an anti dilutive effect.
