For every complex problem there is an answer that is clear, simple and wrong.
Corporations are necessary for specialisation, e.g. even knowing what your legal liability is, having someone to enforce health and safety rules, being able to run a production line rather than having one person spend about a year making a single car.
We can't get most of the interesting things we see in developed economies just by sole traders hiring someone directly for each thing without a corporate structure, partly because that too is a specialisation, and partly because that's way too fragile (every such thing either has a bus number of 1, or it's a mediocre reinvention of a corporation).

Could be. There's a reason we don't see aliens in the sky.
A the same time the "miracle" of collective action that you want to get rid of — because everything corporations do wrong is also done by other kinds of co-operations — isn't really just corporations, it's everything that makes us primates.
That's why you need to be more precise than "just ban them all", why the simple and obvious solution is wrong.
