Yep, government will have no choice but to take some company profits, in some way, as companies will be the only entities with any money.

We might want to look at a sovereign wealth fund, like Norway has. The government could buy up 40% of every stock. The growth in company profits is about to go hyperbolic, now that they won't have labor costs. It might be a way to redistribute wealth from companies to citizens that isn't as adversarial as high taxes (which are also very easy for companies to avoid). It would also align the interests of companies, citizens and governments behind growth.

Just a thought.
