I agree. It's fine to let something stay a side project. Having a company setup that pays for a lifestyle and stays fairly passive is a success based on the original intention.
Founders can look back and say "I could have had more" or "I could have been like X multi-million dollar company", but then the company is no longer a side project. Then the company is your life, which seems contrary to the initial motivation if the point of a side project is to not work 24/7 in a CEO lifestyle filled with meetings and managing.
