Scenario one: Pocket $500k/year profit over 4 years. At the end you've got $2 million saved up and can probably sell the business for another couple million because it's lean, proven, and profitable.
Scenario two: Spend that $500k/year on salaries while trying to build a much larger business. If you fail you could walk away with nothing and selling the business isn't all that profitable because the burn rate seems to be high. Even if you succeed you've likely given a lot of equity away, it may take much longer, and your share might not even be as much as if you had taken the other route.
