I have no idea what your point is. Do you want me to prevent copy construction too, just because copy assignment is not possible? Or do you want me to make the members non-const so that copy assignment is possible?

If the former, why?
If the latter, I suppose I could do that. I'm not the one who made the members const in the first place.
