That is always the argument isn't it? Because of Greed.
Your question was "What’s the point of this??? You answered your own question.
The answer is always greed. i am still stunned at how anybody ever thinks that anything made or released to make money is for anybody other than those who stand to profit from it.
Did they make the movie Interstellar because people wanted it? No, they made it to make money.
Did they make a steelbook for Interstellar because people wanted it? No, they made it to make money.
Are they releasing it again just because people might not have it. No, they are releasing it again so that people will spend money on it for Warner Brothers to keep.
When will people get it that movie studios don't give a **** about you?
It's not about you. It will never be about you.
Until it's free it will never be about you!!!!!!!!!!!!
And of course nobody is "forcing" anybody to buy something because it has 4K.
