Outpost Creation as it Relates to pawn structure

It has been awhile, but I seem to remember Icelandic chess talent Agust Karlsson giving a lecture at Exeter Chess Club on the topic of establishing strong outposts for Knights in particular. One of the more secretive United Kingdom club members defined an outpost to be any fourth, fifth, sixth, or seventh rank square that could not be attacked by enemy pawn.

In the following position, Egypt player player mary-wagih19, had played in a desultory(A Bisquier favorite term, he even told me once word originated from acrobat during a delay between rounds at a Goichberg tournament at Casino in Las Vegas) sequence of opening moves leaving his Queen side pieces uncoordinated with no hope of rapid development(a very difficult concept to define according to IM John Watson and GM Rowson)

So would you take the Queen on c5 with Rook or Pawn? The answer is easy if you think in terms of outpost creation! Any decision in chess has an attendant price which in this case would be a weakened Black pawn structure with the compensation being outposts at b6 and d6 squares. This harmonizes with Horse hopping to c4 to occupy either dark square. 

The stockfish software "believes" the pawn recapture is correct and I doubt children's chess teacher Amanda Mateer would disagree!
