Fizzer would need to change the interface, so the script hits the wrong place, but that would be easily correctable by the script runner.
The buttons are already dynamically created, giving them different ID's each time. The only thing that could prevent such scripts from working would be randomizing the text in the buttons, but that would also quickly get fixed by anyone with such a script.
And I doubt it is worth fixing, since only a few people play games where they have 0 income and 0 moves to make.
P.S. If you need an auto clicker yourself, feel free to mail me
