Corporations don’t provide goods or services: people inside them do. Corporations are a legal structure we allow to exist because it enables jobs and taxes.
Corporations don’t have to exist; they are a creation of society and thus can - and I think obviously- should be changed
Have you ever done anything together with a group of other people? That is a company. That's why they are called companies. They are a group of people doing things.
That has existed for millions of years already. First as hunting companies, then as raiding companies. It exists in other species as well. It will never go away. It has existed in every human society, no matter what political or economical ideology.
The real question is how companies should be organized and owned.
Not even remotely true; corporations as we would recognise them today pre-date the legal system as we would recognise it today (and have existed in just about every legal system since).
Certain configurations of the corporation are described in our laws, e.g. "limited liability".
