As others commented already - the author does not seem to understand principal idea behind running a business - a company is not something "yours", because you can just simply sell your shares or be moved out from the company by other partners.

Company is a state's legal entity given to designated people to manage (the forming person/partners) and profit from doing it successfully. If those people fail they have to follow strict rules (liquidation) or they will be sued personally for misconduct. That entity gives much more possibilities because it is limited liability - part of which is held by the state, and part by the running founders.

If you want something yours, you go with the sole proprietorship.
