You're effectively asking why universal constants are the value that they are. Eventually there's no answer other than "it's a property of the universe we live in that we observed."

If you keep asking why eventually you'll reach a ratio between two values: constants and you can't really go further deeper than that. Even if the values we have now end up not being the most fundamental, eventually you'll run into the fundamental ones and still have the same question unanswered.
