I agree, though I would have thought Disney was more cautious about the potential for political instability. Not that the CCP will fall or anything like that, but the potential for some international conflict that would see the park close or be seized by the Chinese government.
That said, they probably made a reasonable wager that the US government won't put sanctions on China the likes of which we are seeing on Russia and that China will try to stop short of doing anything that would cause US & other Western companies in the country to leave en mass anytime soon. The damage to both sides would like just be too great in either scenario. The other calculation is probably that if they ever do have to abandon the resort, Disney can afford to take the hit so it was worth the risk.
