:Because the movie theaters make 95% of their money of popcorn, soda, and candy sales. They make VERY little of showing a movie, that's why the price for refreshments is stupidly high. Allowing people to buy a movie the day it was released would be nice, but would put theaters out of business.
Furthermore, the studio's profit margin is WAY higher on theatrical releases than on home video sales, and always will be. Studios only release a movie to home video once the revenue stream from the theaters dries up.
