I'm starting to become fatigued by all this TikTok news. Either ban the app or don't. Causing anxiety over TikTok without any action is the worst of both worlds.
It's an interesting problem to solve though. For one thing, there are lots of US investors who will lose money. Should they be made whole?
I mean, think that through for a second: if the government had to compensate everyone for the negative impact of legislation, it would be almost impossible to pass laws. If my town says I can't burn tires in my back yard, do they need to pay me to shut down my tire-burning operation? What if I don't even have a tire-burning operation, but I could have started one, except now I'm prohibited from doing so... did they impair the value of my property by prohibiting a potential use? What about all the other things I could have done with my property, absent any pesky zoning restrictions, Clean Water Act rules, or just centuries of common law precedent? Do they have to pay me for the impairment of each of them, each time a law is passed that eliminates a hypothetical option?
No, of course not, because that would paralyze government and be ridiculous.
The government has no responsibility to make anyone whole if they decide someone's business model is counter to the public good and make it illegal. It's on my investors to take into account the risk of legislation that might impact the business and factor that into their investment decisions and subsequent valuation of the business. If they do that poorly, or fail to recognize a legal risk, that's on them.
This is literally why sovereign immunity is a thing.
