Building complex organizations with managerial structures and shareholding agreements, and so on, through voluntary agreements is perfectly compatible with libertarian philosophy.
Unfortunately, this is not all that “corporation” means today. The modern corporation is wholly a creature of the State and is, in large part, an extension of the will of the State.
I will give one example to help illustrate the point. I work for a very large corporation. Many companies used to pay out a “Christmas bonus” - I don’t know how common this is anymore - and the company I work for gives bonuses, as well. However, the bonus payout is now made at the beginning of the year, rather than the end of the year. How does that matter? Well, IRS tax rules cause the payroll department to deduct taxes for each “check” as if the amount of that would be the income throughout the rest of the year. In other words, a bonus payout check looks like the paycheck of a very rich person and is taxed like it… 40% FICA + payroll + State, etc. etc. Few people see even half of their bonus check. You will get the balance returned the following year after filing tax forms with the IRS and State. In the meantime, the money that you have been paid is just “out there” - you are not paid interest or any compensation for the withholding of that money.
I don’t know precisely why the company pays out at the beginning of the year rather than at the end of the year where the tax adjustment could be made much sooner. But I haven’t the slightest doubt that this must be the result of tax rules/regulations that set up the incentive for the company to pay out at the beginning of the year rather than at the end of the year. In this way, the corporation assists the State in robbing its employees of a massive chunk of change (we’re talking billions) for the duration of the year until tax forms can be filed the following year.
It is true that the interests of the State are not completely in line with the interests of private corporations. After all, the State would love to capture 100% of all corporate profits for its own use. Machiavelli wrote here about the tension between the nobles and the people and how the Prince (State) is situated between these two forces. The corporate Elites are the equivalent of the nobles in Machiavelli’s analysis. The power of the State rests in this tension between the people and the nobles, that is, between “workers” and “corporations”. Whenever it is convenient for its own interests, the State champions the cause of workers against the corporations (raising corporate taxes, increasing taxes on higher incomes, etc.) and whenever it is convenient for its own interets, the State champions the interests of the corporate Elite (catering to their lobbies, adopting anti-competitive regulations, etc.)
In summary, any view of corporations as simply either “good” or “bad” is too simplistic. The idea of a corporation qua corporation is perfectly compatible with libertarian values. Nevertheless, corporations as they actually exist are decidedly anti-libertarian.
