From Graham Cooper:

Here a YouTube vid by DavidButlerAdelaide where he presents a coherent case for what you are advocating:

"Pi may be wrong, but so is Tau!"
I expect you are familiar with this, but others may not be. And discussion on this issue would not be complete without considering these points, for whoever may find them persuasive.
