3/4" flooring is stiff, comes with minor bows, warps and curls, requiring
a
large rubber mallet to convince it to lay flat and fit the tongue of its
neighbor, finally you anchor it with a number of steel cleats (nails) to
keep it in place.

How would you do this with glue? As soon as you release it, it will go
back
to its original shape.

I know of no manufacturer that recommends gluing wood planks of this
thickness. Only engineered flooring, which is a plywood type material is
stable enough to be glued, and I can imagine that sometimes there can be
problems with that material.

Read my post. I recommended against gluing the 3/4" as well. There are
some places that do advise that it can be done but I don't subscribe to
this. Most if not all, Hardwood Mfg's do say you can glue 3/8" -1/2"
planks.
