I don't believe in it at all...
Just go headlong into the Queens Gambit and 2.c4 imo.
You say "I would rather arrive at the middle game with winning chances than being down a pawn or two with a bad position."
However, you should remember that you are more than likely losing material due to tactics you need to familiarize yourself with. Don't play the London System. More broadly: Don't avoid your weaknesses.
Get familiar with QG and Indian Defence positions and explore common themes. As white, you should always strive for an advantage.
I purchased the fritztrainer opening DVD “Build A 1.d4 Repertoire” by GM Nigel Davies. Nigel thinks it best to delay playing 1.d4 2.c4 until after playing one of the more simple queen pawn opening systems for 6 - 12 months, i.e., London, Colle or Torre. The reason being that there is more opening theory associated with 1.d4 2.c4.
Having committed to 1.d4, I finished viewing both “Build A 1.d4 Repertoire” and “The Colle System”, and ordered the “The London System”, since Nigel believes that the London presents the fewest problems to the player new to 1.d4 and doesn’t require the same level of urgency as do the Colle and the Torre to play 1.d4 2.c4.
Considered dull and boring, these three 1.d4 systems are not nearly as sharp as the Queen’s Gambit, but for the beginning chess player attempting to play Live Chess, I would rather arrive at the middle game with winning chances than being down a pawn or two with a bad position.
The Queen’s Gambit works fine for Turn-Based chess. I have chess books and more time to think. :)
What do you think about the idea of building a simple queen pawn repertoire before upgrading to 1.d4 2.c4?
