This is an old, and seriously flawed argument.
You are not wrong about this!
... the argument assumes existence is a pre-requisite
for perfection. In reality, anything that exists can never be perfect.
But on this specific thing, it is more complicated. There are a
few different strands of argument of this general sort. One of
them is about examining the concept closely and finding in it the
idea of a type of existence that is different to the existence of
ordinary things. If God exists, he does not exist in the same
sort of way to the way a brick exists. A brick could puff out of
existence, but it would be more than silly to suppose that God
had such a a precarious type of existence. His existence is much
more like the existence of classes or numbers, the prime between
6 and 9 could not just disappear or not be in the way that a
brick could disappear or not be. There is a quality of necessity
to Him, in the very idea of Him - so the theists say.
In the end, this fails, but not for nothing has it spawned such a
vast literature over the centuries, especially in the 1950s and
60s.
For example, say anything that exists has a height. If that height is big,
then the object is too big to fit into my little gold box, so it can't be
perfect, because to be perfect it should be able to fit into my gold box.
No, there is a scope problem here. Something can be perfect in
respect to certain parameters. Tables for tabular data. It is not
a mark against a hammer that it it fails miserably as a
screwdriver. It is not a mark against God that he is an obstacle
to a thief who has a sudden consciousness episode... But
existence - so it is claimed - is very much a relevant parameter.
God is the ground of all being and all that...
Ho hum...
