Linux phones are not going to be daily driver worthy in a long time.

My friend's daily driver is a PinePhone. So daily driver worthy.

Another thing about those support layers is that banking apps usually know how to detect rooted devices and stuff like that and won’t work.

Android emulation layers emulate secure, non-rooted devices and banking apps work.

That's unfortunate but it is what it is.

No, it isn't.

Banking apps run in Android emulation layers on GNU/Linux. Your bank doesn't need to support Linux phones.

An Android phone isn't what's referred to when people say "Linux phone". What they're referring to is a phone running GNU/Linux, typically running one of the GNU/Linux phone shells/desktop environments.

Android is Linux.

It runs Linux but it isn't a "Linux phone" in the sense used here.

My friend's daily driver is a PinePhone. So usable as a daily driver.

What you've said here doesn't contradict what I said. A phone running Lineage OS is explicitly not what people are referring to with the phrase "Linux phone".

I know

Apparently not.

projects like GraphneOS/LineageOS ... our best chance at getting "Linux phones".

To repeat myself: an Android phone (for example, running GrapheneOS or LineageOS) isn't a "Linux phone".

Edit: I don't want to buy a phone. ... Sorry for the bad wording.

I'd suggest editing the post's title as well.
