I'm completely with the OP.
Maybe not on this particular case, but more and more players aren't coached to take players on (and risk losing possession). They aren't coached to take risks or do what might be considered difficult.
And Van Gaal certainly fits into that category of a manager who prefers his players not to take risks. We just had Rooney and Carrick (apparently) say they are unhappy to LVG about this very thing.
To me, it seems there are two types of players at the club. 80-90% will be taught to contain, the stick to their fixed roles and to play the same triangular passes so as not to lose possession. Players who used to go into the second category may fall into this one over time, if the club thinks they have lost some pace or quickness. Carrick would fall into this category "all he does is pass backwards" (late 00's) or Rooney "Why does he not score goals anymore", or Valencia "he never takes players on anymore"...
Or Januzaj.. he was a creative player who would probably lose possession much more than he created something at the moment, but LVG doesn't want to take risks like that, so he's been shipped out.
Welbeck was another one, frustrating to watch as he misses more than he scores, so shipped out straight away.
Even the Netherlands at the World Cup were devoid of creativity after the group stage.
Now that's not say that I blame LVG.. it's actually just the way Football is going. Arsene Wenger has been turning his side into a team that doesn't know how to take people on for a decade, and so to some extent has everyone else. If you look at what Arsene was saying about strikers only coming from South America, there are clearly some big problems in creating outstanding European footballers other than midfielders.
