One Unit

וְנָ֨תְנ֜וּ אִ֣ישׁ כֹּ֧פֶר נַפְשׁ֛וֹ לַי״י֖ בִּפְקֹ֣ד אֹתָ֑ם וְלֹא־יִהְיֶ֥ה בָהֶ֛ם נֶ֖גֶף בִּפְקֹ֥ד אֹתָֽם

How does using the half-shekel to count work to avoid the ayin harah?  What is the issue of counting Klal Yisrael?  When one counts every individual that means that every person is a unit of themselves.  There is no togetherness.  That is the issur because there is a cohesive body of Klal Yisrael that is one part, not a gathering of a bunch of individuals.  The lesson of the half-shekel is that every individual needs another half to make them whole.  Everyone is not their own unit; they need someone else to complete them.
