Why do we need 'Legal Persons in contemplation of Law', when we have the 'Real Persons'.

Why do we need 'Legal Persons' in 'Contemplation of Law' when we have the 'Real Persons', and why do 'Legal Persons' need 'Constitutional Protection'? Doesn't sound right, doesn't look right and is 'not Right'. We have to ask, why do we need more Legal Fictions? 'Legal Fictions' may be necessary to connect Legal reasoning to its subject matter, like the Reasonable prudent Person, but why do we create a Legal Fiction in the Economy when it contributes to 'Monopoly' and 'Self-aggrandizing' and when it 'displaces the 'economic position', and value of the 'Real Working Person'? Most Individuals would agree that Legal Fictions do not belong in the Economy because economy deals with 'Production', Money, and Profits. A 'Business Corporation' is an 'economic entity' and should not be considered a 'Real Person'. A Business Corporation just makes Profits. Certainly, it provides the Socal with 'essential products' and 'contributes to their availability': but why does it need Constitutional Protection? Does an Economic Entity need protection so that it can contribute towards 'Monopoly', 'centralization of Monies', and the 'creation of Economic Classes'? If the Business Corporation is considered a 'Legal Person' and functions as a 'Real Human Person', namely; contributes towards 'Democracy', it may not be a bad idea. Of course, 'small changes' in the 'Structure' would have to occur. But, thats not the case; the 'structure' functions like an 'Autocrat', and it gets 'Constitutional protection'. We have to ask, Why?
