It's assumed that corporations spend as little as possible on operations. Individuals obviously don't. Whereas a corporation wouldn't rent employees 500 sqft / person, individuals regularly rent/purchase that density for themselves. Similarly, while a corporation might buy a Camry and run in into the ground, some individuals will buy a new BMW every 3 years.
Corporations also don't have a motive to exist beyond profits. If you tax revenue and make profits untenable, then corporations simply will not exist. Individuals on the other hand try not to die.
