Another great example is an enterprise.
Simplified: while there is an owner, the enterprise itself is a separate entity, the owner can’t just take or put in money on a whim, without any valid reason. There are rules about money flow and taxation and the enterprise have responsibilities like payroll. You can get a divident, the enterprise can pay salary to the owner.
Technically the your own enterprise can give you a loan, which you would owe to the enterprise.
