Domain name registrars aren't normal companies. They're more like a government institution. The government can't refuse to recognize the fact I own my house just because they don't like my political opinions. Why should it be any different with internet domain names?

It's not about agreement or disagreement, it's about monopolies.

I am fine if the government takes away the freedom of corporations to grow arbitrarily large.

I am also fine with the government making corporations choose between the ability to grow arbitrarily large and the ability to kick off users without due process.

There's no need to take any freedoms away from normal-size companies.

There are already laws in place that do just that.
