That was the "conspiracy" called co-operative behavior. And to keep certain skills, etc in the family and later an association of like minded people defined by skills and monetary interests, well that was logical because what THEY could do was worth a lot of money, which begets power, so the "secrets" were what we today call a job skill set. Not so diabolical when seen in that light and was guarded as trade secrets are today. Its all about the money, always was and is.

What remains to be explained, to me, is how they made those square "pits" in the middle of the stones, because even if they used some kind of drill to make those small holes that would help break the stone, that method works when we can move the two halves in opposite directions, but when doing that in the centre of a stone we cannot make the rock break only in the centre without breaking the whole stone.

The problem I see in that is that a copper chisel would probably be used only once or twice, as the sharpen end would become dull (I think that's the right word, sorry if it isn't ).

No. Once sawn, the chisel need only break the stone in the corners.
But the same problem arises, copper is too soft for that, just some hits against a stone would mess up the chisel.
Roughing out the smoother surfaces can also be accomplished with a chisel - without making cuts - by merely directing the pounding force to one small area at a time
I know, I have beein doing that for some time with my balcony.
Smoothing the surfaces can be accomplished by rubbing with other stone.

What I think is that copper, while useful for something like a hammer or even an axe able to cut wood would not be as useful as a stone tool against stone.
Close examination of some interior
angles of the precisely wrought stones reveals, even to the
naked eye, a fine groove in the very apex of the angles. We
suggest that these grooves result from the blade of a chisel-like
tool, and that the point in which the four planes meet was
made with a punch-like tool. No such tools have been recovered
or recorded, but other details at Tiahuanaco suggest the
use of chisels or punch-like tools. Several recessed pockets with
T-shaped cramp sockets (discussed in more detail below)
carved into them allow one to determine the tool's angle of
attack and its minimum length [Figure 22].
The known and documented tools of the Inca construction
trade are hammerstones, bronze pry bars, plumb bobs, and
ropes. Although several exemplars of chisels are held in Peruvian
museums, judging by the tool marks on building stones,
chisels were not used to cut or shape them. Evidence in the field
points to the occasional use of some sort of saws or files, and of
grinders.39
STONECUTTING
To rough out, shape, and finish building blocks, the Inca
stonemasons pounded or crushed the work piece with hammerstones.
On roughed-out stones the technique leaves diagnostic
pit scars made by the impact of the hammers and patterns of
cup-or trough-like depressions reflecting work in progress. On
finished, or finely dressed stones, it also leaves pit scars: large
scars in the center of a stone's face from large hammers, small
scars along its arrises from small hammers. The particular
technique for drafting edges on a block results in dihedral
angles that are typically in excess of 90?, making the stone's
faces bulge out, pillow-like.21
Pit scars and patterns of cup- or trough-like depressions are
found on several roughly hewn and shaped stones at Tiahuanaco
[Figure 20].22 Although we have yet to find the actual
hammerstones, the marks suggest that the Tiahuanacan stonemasons,
to do the coarse work, used a technique quite similar
to that of the Incas.23

No doubt it would, if it was sharpened.
I'm saying it would be used more like a "chipper" than a "cutter" to break free the stone after the saw was used.

Perhaps steel or actually iron was so basic before the bronze age but keep in mind, it takes a lot more heat for iron to get hot enough for impurities to be a lesser issue.
