The government should just pass a law banning capitalism and then we wouldn’t have to worry about strikes at all, but that’s also never going to happen.

That doesn’t mean it’s a bad idea, just that it’s too extreme by the standards of US politics. Unions here often still need basic protections like the right to strike at all in the first place. Check out the rules against teachers striking in Texas, they’d be banned from public sector work and lose their pensions. The only way they could possibly go on strike is with a vast enough majority to force the state government to repeal those rules.
