I agree that the system is going to effect how nations plan and react.
But the ROC can impact and degrade those systems and their effectiveness when operating at range targeting or intercepting aircraft over their island from the mainland.
My principle points still stands...it is HIGHLY unlikely, and would be folly, for the PRC to place these systems in a position to act like an offensive weapon and seek to control flight over other nation's sovereign air space.
S-400 is mobile . One day it could be stored somewhere in central China, and other day it could be deployed on prepared position across Taiwan . China could deploy S-400 to monitor air traffic over Taiwan (with limitations in coverage below certain attitudes and in radar shadows) like any other radar system .
Would they actually use it , i.e. would they fire on aircraft over Taiwan ? Well no, unless the situation escalate to the point of war . But remember that China considers Taiwan to be part of itself . So, from Chinese perspective, there is no legal reason not to use it when they decide to use it .
From Taiwanese perspective , it's another thing they would need to worry about . To put it bluntly , airspace over Taiwan above certain altitudes would be a danger zone 24/7 , no matter how far are Chinese fighters .
