The idea behind penalty points is to filter all the people that aren't engaged or taking this competition seriously enough to lower leagues and allow true sport fanatics to be in first 2 divisions.
agree here, penalties should be there (as you put them)
and one can see that both relegated teams from Div1 (nothing personal against them, contrary, just stating facts) had penalty points this season
so one can see that penalty rules are doing what you have said in your intent to enforce them
