I wrote that off more as his hyperbolic douchey style, but sure, a secret infinite flat plane would be valuable.

Note that I think his previous science based arguments are technically stronger. But focusing on the numbers of people who would have to be 'in on it' is an interesting approach. It's not 'proof', but it stretches the credibility pretty far.

I'm going to try to watch that one again to see it from your perspective.
