Food trucks may need to scale because you have to buy additional food, maybe hire a few additional people. No lemonade stand, unless you already have the lemons. You'd think blogging on a free platform might fit the bill. But, making money depends on readers, which would need to scale to make ads worthwhile, so scratch that- it's scale-dependent. Don't do that. Maybe if your family has a lot of money, you could pay someone to write your app for you. No- scratch that- it's dependent on the number of people paying for it, and you need to buy ads to reach them, so it must scale. You could be an investor! Just hold out a carrot and watch people work themselves to death while having a small chance at success. Even if only 1 in 10 you end up actually giving money to for their work are successful, you come out on top. Wait, it turns out 1 in 10 isn't guaranteed. That won't scale, then. Instead of investing yourself, have someone else invest it for you. Nevermind, no one would do that, because in order for it to be worth it for someone to invest for you without taking too much off the top for overhead, they'd have to scale. Back to selling.. you could sell your existing possessions and evengelize, going from place to place to get food and lodging. Sounds a lot like being a priest.
