Hmm - I’d like to know what I’m doing differently because It definitively doesn’t do it for me. As I say I’m grateful for the option key - but it’s only half the fix.

Are you checking the box next to "Show Library Folder?"

If you check it, close the View Options, then open them again, is it still checked?

Thanks -- it gets me part of the way there, though this only works with the option key -- I'd like to be able to lock it visible.

That was the first line of my answer.

Was the checkbox missing when you looked?

This thread seems to indicate it might not be available unless you first open the Library folder.

Open the View Options on the Home folder and check the box to show the Library.

Or, just hold down the Option key and select Library from the Go menu in Finder.

No, that doesn’t work - I wish it did

It works for me and everyone else.
