Neither a pizza place nor a startup exist in for very long without revenue exceeding expenses.
Even in your own examples, both businesses work. It doesn’t matter whether it’s from low revenue and low expenses or high expenses and high capital injection.
Show me a business where revenue was ahead of expenses, had no debt, and it went out of business because it couldn’t pay its bills.
There’s no amount of surprise gotcha clever but-actuallys that can argue with you’re either making money or you aren’t.
I’m pretty sure “literally everyone” understands that, and not “literally nobody.”
