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.
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.
Did you even use Finder or are you just trolling?
The actual keyboard shortcut, if you'd like to reproduce the behavior you get with Cmd+L in a browser, is Cmd+Opt+C Cmd+Shift+G Cmd+V.
