If majority of the company operates in US did not comply on the law then maybe we can see a major downfall of crypto industry in that country. But if they didn't do anything like what this guy accused Binance or any other crypto companies then they have legit documents to show for sure with this they can fight this guy who want to disturb the crypto operation and its widespread in US. For now its good to follow this case to know what action does Binance will do with their case.
Most companies that want to operate in the US market need to apply for a business license and pay taxes. That means the US government is collecting a significant amount of taxes from the crypto industry, so I don't believe other politicians will let the SEC destroy that. The SEC is not the ultimate authority on this matter, so destroying the entire crypto industry in the United States is unlikely even if the companies continue to fight the allegations of the SEC.
Binance.us only accounts for a small portion of binance's global revenue, so they're willing to give up the market if the SEC puts a strain on it. But the problem is that other exchanges only operate in the US market, what will they do?
