Fix this in your OP
=================================================================================================================
Take two share classes in the same company. A and B. Both worth 100p.
A pays a dividend of 5p. On XD day the share price falls by 5p (plus other market movements). You now have 95p in shares and 5p in cash. You still have 100p.
B pays no dividend. There is no XD day. You still have 100p (plus the same market movements that affected share A)
There is no actual difference between selling 5% of the shares and taking a 5% dividend.

It's nonsense
