> I see nothing wrong with adding Tail Call Optimization to Python.

That's nice. Is that supposed to be an argument that convinces us?

You are hardly the first person ever to suggest TCO for Python:

Unless you have a more convincing argument than the arguments previously made, and rejected, this ticket will be closed.

Even though this has been rejected in the past, the door is not quite closed. In a couple of weeks, Guido will be replaced as BDFL, and the new governor(s) may be more receptive to this idea. But you will probably need to write a PEP.
