As a social function, companies as an _institution_ are there to benefit lots of people (like owners, employees, customers, investors, etc).

But individual _companies_ are under the controls of their owners (modulo applicable laws). That's because we empirically figured out that this model works well, and also because we want to incentivize people to start and run companies in the first place.

Also keep in mind that in some sense companies are just legal shells. If you strip assets like eg machine tools, in order to make money you actually need to sell them. But if you do that, someone else has them to use them. They don't just disappear.

Yet another thing: not all companies should be kept around. It's good for less inefficient companies to go bankrupt, and for people to change jobs. (Especially as long as the overall unemployment rate is low enough. But you don't keep that rate low by making it harder to fire or harder to 'pillage' companies. Just the opposite, you get more job creation the easier you make it for people to benefit from creating companies and jobs.)
