EGR-quick question

i read all the discuss and opinions in the search on EGR, .... i have a 72 and 76 s/6 dusters, best way to get rid on erg in intake? some say just leave it in there? and why can't i just weld on the little hole shut on thanks EGR plate on side of exhaust? i've had bunches of the pre EGR cars so i have learned to dislike excessive vacuum lines and needless "stuff"!
