As already discussed, the argument that top players who emply a 'blocking' strategy are lazy is completely baseless. To put that into more perspective, let me help you.
You play your ideal game where you get dealt decent tickets at the start, build them, pick up more tickets, complete them, and end the game with 3-4 16+ point tickets and about 5 shorter ones. Althogether you have about 100 points in tickets, along with whatever points you got while building your routes, which means you probably have a score in the 160-170 range. At the same time, your opponent has gotten 2 short tickets that are worth about 15 points, and even if they got 90+ points off routes, their final score will be about 100-110. So if your opponent wants to win, how are they supposed to do it? They can't draw tickets because you have already taken the best ones, and they can't sit there and hope you miraculously run out of trains, or something like that. The only way to for them to win is to stop you from earning a whole lot of points. Remember, the idea of the game is to score more points than your opponent, and a good way to do that is claiming lots of long routes, blocking opponents critical routes and ending the game quickly. Admittedly I used to play just like you, and very quickly after Ticket to Ride came out on BGA I figured out that in order to get better I had to start using the build long routes end game quickly strategy.
As for the lazy part of it, I would totally disagree because the strategy is not lazy, it is a legitimate strategy in the same way taking lots of tickets and building them is. The difference? Players who play by getting lots of tickets are rated 100-200, players who block, claim heaps of six routes and end the game quickly are 600+. As someone who employs both strategies, I am mid 400, however its is very clear to see that playing the game to score 100 points mostly from routes is better than aiming to complete a whole lot of tickets and scoring 150 points. People who block and score low are not lazy- rather it introduces more planning into the game, makes it more tense and interesting, and if you win one of those games, you feel a lot better than if you win a game where you scored heaps from tickets and your opponent basically had no chance because of their luck.
(PS- I know this post is long and probabbly makes no sense, but it basically says that people who play the game like you describe are not lazy.)
