Idolatry and religion

Greetings to the rabbi.
Someone makes a claim that I think has some truth to it, and that’s why it bothers me. I’d love to hear your response.
He says that the God of Israel commanded not to make any image or likeness of Him, in general, to simplify God as much as possible and to distance himself from the fulfillment.
If this is true, then all religion is a form of idolatry, because if God needs to be simplified as much as possible, the more preoccupation with Him and the connection to Him fulfills Him. The religious person creates an image (even the most abstract, but still a God of some kind) of God. The most correct thing to do if you want to avoid idolatry is to not bother with God as much as possible and to ignore Him.
There are some holes in this theory, right (just as philosophical thinking about God is also a fulfillment, so how do we know that he exists at all) and yet there is something true and disturbing about it. I would love to hear your opinion.
