Set up the garden’s walls so you can profit off the users when “eventually” figure out how to monetize them? Sending people to third party sites means you can’t show them ads even in principle, but the cost of hosting seems like it would quickly outstrip whatever extra revenue you could get. Corporations are legally required to increase in value forever, so it’s literally illegal to make “enough money” when there’s a chance for “all the money”, even if pursuing that chance actually hurts long-term viability (which stockholders don’t care about because they can always cash out).
