Because limited is the only format where you don't just copy a list that someone far better at you at Magic won with so that you can attempt to pilot it to victory, riding their coat tails.
Luck is an inherent part of the game, whether you're in constructed or limited. Luck in constructed is minimized through testing and finding how to build around a strategy that offers the most consistency. Consistency is found in limited by having an eye for what cards are weak and what cards are strong when building a deck and finding a balance. Unfortunately, people who play almost exclusively constructed aren't that great at limited because cards that they don't want to play in their constructed decks that they consider "bad", can often times be amazing in limited. This is why I laugh every time spoiler season starts and the waves of whiners about limited "filler" come out of their holes. The majority of players on the internet are copying lists of far better players whereas it's far more of a test of skill to play limited where you can't just copy a list from the latest Grand Prix or PTQ winners and go to town.
(As a side note, I'm not a "rogue decker" nor against net decking; I just find find it amusing how full of themselves some players are. I remember when posters in the Rumor Mill said Tarmogoyf was bad, that Elesh Norn, Grand Cenobite costed too much mana, or when Tooth and Nail was terrible. Glad I picked up a set of Norns when they were $4 each, before they hit $20+ when she was Standard legal. Just a few examples of the masses not really knowing good cards until someone tells them, ie. a top 4 list somewhere.).
I agree with every word of this 110%. I play standard as well, but I have found that the absolute worst advice on card evaluation and decklists are found in the standard forum. Well rounded and skilled mtg players generally play both limited and constructed, players who only play standard are generally the most myopic about this game, and I've found that they just regurgitate whatever decklist and/or article they read that whoever is better than them came up with and accept it as gospel.
I agree, the real skill in limited is actually playing the deck you constructed.
