>the slow population growth in industrialized countries indicates that depopulation is possible

Slow population growth, does not lead to depopulation.

(Not that we would need depopulation anyway. More just a point that slow growth, is still growth.

Your point is, of course correct: slow growth is growth. However, it worth clarifying that population growth in much of Europe is driven by immigration rather than natural growth, and therefore does demonstrate population decline which is offset by other regions population growth.
