You can be christian and not like the pope.
But to catholics, the pope is the terrestrial embodiment of the holy spirit, and as such considered infaillible. Not recognizing the pope as such is incompatible with catholicism.
Papacy is a core part of catholicism, it's not a "pick and choose buffet".
This is a common misconception. The pope is only considered as speaking infallibly by the Catholic Church when speaking ex cathedra on matter of faith and morals. This is very rare and is considered to only have happened twice in history.
I come from a Protestant background, so I view Catholicism as just Protestants with a pope. What does it mean to be catholic but without a pope?
Catholics owe the Pope religious submission of intellect and will to his authentic magisterium (teaching authority) on faith and morals, even when not speaking infallibly (Lumen Gentium 25; CCC 892; Code of Canon Law, can. 752). This is a respectful adherence and presumption in favor of what he teaches officially as Pope. This does not extend to his personal opinions, private theological views, prudential judgments (e.g., on politics, economics, or administrative decisions), or liking him as a person or agreeing with everything he says or does in a non-magisterial capacity.
The Church certainly disagrees with you, teaching that the visible Church is the ordinary means of salvation and full communion with Christ. (see the Precepts, CCC ~846–848)
I'm not even sure from what position you are arguing from, but both of those statements (relationship with God supported by a visible church rather than requiring it, and Matthew 18:20) are fundamental arguments for Protestantism.

If we can agree on that we are closer than you might think. And when I said "not dependent on the church" i was referring not to what I just defined above, but rather what in my head i figured (perhaps wrongly) you were more narrowly referring to.
To continue, at risk of muddying the waters that might have just cleared a little, the nature of the church (a divine mystery) is such that it can be known experientially while never being fully exhausted by human understanding
Famously the French got rid of theirs, several times. Maybe not the best example.
You can be French and not like cheese.
Wait, no, it doesn't work.
Quick, read the Nicene creed aloud right now...
I don’t think you can? You know how that worked out? It’s the OG ‘No Kings’.
