If the universe came with any old rag-bag of laws, life would almost certainly be ruled out. Indeed, changing the existing laws by even a scintilla could have lethal consequences. For example, if protons were 0.1 per cent heavier than neutrons, rather than the other way about, all the protons coughed out of
Another new scientist article shows how this may be true but wrong.

It is possible to construct universes with pretty large changes to the laws and still get a life supporting universe.
What we don't know is:
How many combinations are possible.
How many of those are life supporting and how many are not.
In other words the whole argument is spurious since it pretends to suggest an answer for which we have none of the inputs.
