There's a "Show Path Bar" setting accessible from the View menu in Finder. You can see the file's path right from the Get Info menu and drag and drop it into a terminal or whatever and have the path immediately available. You can copy a file's path by holding the option key with the right click menu is open.
It's pretty accessible. Most of the complaints I see regarding Finder seem to be a result of trying to use a Mac in the same way as another OS. It's different, but takes just a quick search to find all the shortcuts and stuff and it's very simple.
These are great Finder tips, but they all involve the mouse, which I find mildly infuriating.
Command-Option-C: copy the full path of the selected file or folder as plaintext, with space characters not escaped with backslashes.
Command-C, then Command-V into a terminal prompt: paste the full path of the copied file or folder, with space characters backslash-escaped. Tested in Terminal and iTerm2.
