This method works better in a free market. Instead of outright banning things, you simply build a system that encourages/disencourages specific things and it basically runs on autopilot.
Except when the AI businesses have lots of available money, so they might not care about the extra taxes (they're spending billions anyway). There's also the problem that they might destroy the future agricultural worth of the land with e.g. polluted waste water.
Given that they don't want agricultural land used for data centers, it makes more sense to just ban them rather than allowing it if they get some extra cash.
