It depends on what task you want to perform, and the design of the individual knife. Wood carving and splitting fire kindling with a dagger, no. Opening packages and cutting twine, sure.
Do a quick Google search for "duct knife", it's a double-edged knife designed for, well, duct work. It's very similar in design to the full-size SOG Pentagon fixed-blade (one plain edge, one serrated edge). In fact, if they were pictured side by side on this forum people would probably think the duct knife was an attempted copy, or at the very least that it was a weapon.
Many years ago I worked at a shipping dock where knives were essential tools. There was an "old timer" there who carried an old Ek commando dagger (from his service in Vietnam). He kept one edge like a razor for some tasks, and the opposite edge with a rougher edge, sort of micro-serrated for other tasks. He never had any difficulty using that knife for utility purposes.
The closest I come to using a dagger for utility is my daily carry Cold Steel Tilite 4. It came with a shaving-sharp edge (which I maintain) and it serves me well for simple tasks like opening packages, cutting cord, and trimming the occasional hangnail, among other things.
"Daggers" come in a wide variety of designs, some better than others for utility purposes. Some have wide grinds with very fine, sharp edges that make them excellent slicers. And some have very wide, rounded 'bellies" which can increase their cutting versatility.
I wouldn't choose a dagger for a trip out into the bush, or for skinning a deer, but I'm sure that in a pinch a dagger with the right edge geometry could be used effectively for several tasks related to such activities (even skinning and dressing a dear).
In my life I've seen survival experts effectively skin game with a piece of broken bottle and the lid from a tin can. In the end, the average dagger is a sharpened piece of steel with a handle attached. And as the saying goes, it's not so much the tool, but the skill of the man who uses it.
