@KamiKira00 I get that but my point being is, every manga will have a plothole or unexplained occurrences that you can pick on.
Some of the best mangas I've read are all from teenagers and people in their 20s, people with little to no life experience at all, yet they manage to write/draw enjoyable mangas.
And Isekai is mostly about shutting down your brain and let the authors manga guide you through it.
Because in the end no matter where your line of logic stands every manga will be disappointing to you.
You just have to let it go, in most cases theres no need for a ground based logic in the first place. Trust me you will enjoy a whole lot more mangas if you just let it go.
