Here's a simpler way to phrase the problem.

The current world population is about 8 billion.

By this argument, and also by your argument, it should actually be 999 billion. Or a number even higher than that.

The conclusion boils down to:

1. Find maximum population number earth can support.

2. Hit that number.

I do think that, when put this way, it seems simplistic.

To be fair, boiling something down to a simple statement does indeed tend to produce simplistic statements

Here's an even simpler way to phrase the problem.

The current world population is about 8 billion.

By my argument it should be 2 billion.

Your argument is therefore rather foolish.
