Ramsets often don't grab in well-cured concrete, the way they do in fresh.
Also - he's not a pro - when is he ever gonna need a ramset again? A hammerdrill will get used for other things, inevitably, eventually.

Just so everyone's clear: I'm the POODLE in the picture ("french", get it?) The hot woman is my wife.
I am in Key West at the moment enjoying the sun.
But I maintain that screws and anchors are the way to do this in the spirit of craftmanship.
I am approaching a gas pipe that runs the length of one wall across the basement ceiling. It is positioned about 5 inches from the wall which means I have a choice.
I can either box it in behind the stud wall (which would mean I could not access it) or in front of the wall but cover it behind the suspended ceiling.
Which is better? I either lose access and a little square footage, or maintain access but lose some ceiling height.
Number one, I don't believe you are allowed to bury the pipe behind the stud wall. Second, 5" is a lot of room to waste. Definitely build the wall against the foundation and build a soffit to cover the pipe. Then if you have to make a repair or replace the pipe it's much easier to get to.
Rerouting the pipe is also an option if it's bothering a lot. More time and money, but you are already investing a lot of time and money to finish the basement. See if there's another path for the pipe.
Don't follow my advice, I only know a thing or two about a thing or two.
