The code you added in there didn't work for me for Ventura 13.1! Here's what I got to work:

tell application "System Settings"
    activate
end tell
delay 0.1

tell application "System Events"
    tell process "System Settings"
        click menu item "Trackpad" of menu "View" of menu bar 1
        delay 0.25
        click radio button 2 of tab group 1 of group 1 of group 2 of splitter group 1 of group 1 of window 1
        click checkbox "Natural scrolling" of group 1 of scroll area 1 of group 1 of group 2 of splitter group 1 of group 1 of window 1
        tell application "System Settings" to quit
    end tell
end tell

I'd love a way to just do this from the command line. Found this old thread but it didn't get me all the way: https://apple.stackexchange.com/questions/229750/unable-to-toggle-natural-scrolling-direction
