That's silly of course, but what about a Ractive? I think something that actively tries to collect data on you and shape your perception controlled by a geopolitical competitor should be handled carefully and potentially outlawed.

Sure, but there are natural guardrails within that... for instance if we decided to call the UK a country of national security concern it would trigger massive diplomatic and trade ramifications. Other than China you'll notice everyone else on the list basically has 0 trade volume with the U.S., so there's not much damage to the U.S. economy, but doing it to other countries would be a major escalation with economic consequences.
