That just seems silly to me. There are fundamentally lots of problems that require the labor of hundreds or thousands of people. You're not building a jet airplane with a team of 25, nor an advanced computer chip, nor, in AirBnB's case, a global peer-to-peer booking platform.
I'm sympathetic to the idea that many companies grow prematurely, or that they grow "just for growth's sake", but I don't like thinking that an answer to a problem is to just pretend it doesn't exist.

Scale tends to bring increased revenue/profits. Starting a business is a massive risk of both time and capital typically. If there isn't the potential to win a big reward, we would have far less innovation happening. Most companies need to attempt to scale to justify the risks.
If you want to risk your time and money without the potential for a big reward, thats great. Start a business, make it successful, and start pumping the brakes as you see fit. However, if you do this just be aware that competitors who are willing to scale may come and eat your lunch.
