How can I set Python symlink in MacOS Ventura?

I am trying to set a symlink so that I can point the

command in Terminal to a new install of python3. I last did this in Mojave, where one could disable csrutil and then run the following command before re-enabling:

ln -s /usr/bin/python3 /usr/bin/python

Now I am trying to do the same in MacOS Ventura 13.1, and I am met with the error feedback:

: /usr/bin/python: Read-only file system

What is this new roadblock that "MacOSimandius, destroyer of worlds" throws in my path? And more importantly (please): **How do I set my symlink?** It must still be possible. This is still unix, is it not?
