These days we are able to find planets from our home planet. It makes me think it is silly to produce a game that takes place over 200 years in the future that is so far behind in technology to what we can do today.
I completely agree, but there are some who like the option of adding difficulty to the game regardless of it's realism. I have known some who try many different things like playing only when they have a toothache, or playing with their mouse upside down. 
I kid of course, the game is plenty hard for me with the various difficulty levels without adding any other handicaps, To each their own.
