Thing is with this is that if Valve does put money into tournaments as they do for their other games it would be a huge waste of money. The problem is that the ranked matchmaking was a huge failure, tf2center which is supposed to be the hub for newer players gets around 200 players which for a competitive game is fuck all and Insomnia that is the main event gets barely any viewers and in other games, insomnia is seen as a low tier competition.
So with no interest in the game if they were to put the money in that would be a huge waste. Most international lans like for Dota and CS take into consideration how many people will be watching the event and the amount of advertisement and merchandise will be sold so that the prize pool and venue will still be profitable for Valve. If there is no initial interest in competitive TF2 putting that amount of money into their game is just stupid.
As much as I love TF2 and want to see the game thrive, Valve have done as much as they can to try and make it work but the fact remains that TF2 competitive is way too small of a community to make a full competitive scene out of.
In regards to the video, though compared to Doomsday's old videos and his somewhat recent Twitter posts, this is actually a really good discussion piece which is well produced.
