I didn't think about it that way but that makes sense too. I also think on some level Gus respects that Mike sees the bigger picture and even though he could just sit back and collect a check, he wants to make the paper trail more legit, and probably deep down enjoys that type of work. So yeah he's willing to go do these things on his own time and would be a good #1 goon for the team, but I think Gus also respects that he's got intelligence and can also be more than just being a hired gun for muscle.
		
		
	 
also, i feel like mike thinks if he can infiltrate that easily, so can almost anyone else. 
if he's going to be doing business with them of any kind, he wants to make sure their shyt is tight. 
as we see in BB later on down the line, the way they have Pollos set up with running the meth, you do not want ANY parts of that operation to be sloppy. 
i'm actually kind of surprised at lydia's reaction. i would think that she would listen to what mike has to say and and take his advice.
