I think this is perhaps the strongest pro-tau argument. How many intuitive insights may have been missed or delayed, because a 2 was factored out of 2pi?

Perhaps a softer stance on the way to tauism is to encourage folks to keep the 2 and the pi together as a single pseudo-symbol 2pi. So you'd never factor out the 2 (A = 1/2(2pi)r^2) nor would you distribute over it ((2pi)^2 would never become 4pi^2). I don't think that would work well in the educational space - now there is this extra weird rule about reductions - but it might help in other fields. At that point I guess you might as well use tau though.

About as many as were missed or delayed because a 1/2 was lost from 1/2tau.
