Well Alex;
Water had to come from somewhere originally, so it beats me as to why this is so newsworthy ??

The problem with the statement is the usage of terms of certainty. (Ie: "This means life
will be everywhere."). Even in speculation, one should make an effort and exercise precision in the wording of the statement. If life is everywhere, then why aren't the little green men on Mars repairing the rovers for us ?
Until an instance of exo-life is found in a habitable zone where liquid water is present, terms of certainty are improper, as they cannot be substantiated with evidence.
I realise you are following a speculative 'line of enquiry' into the possibility that there may be some abiogenesis sub-process in which the fundamental behaviour of water may play a primary functional role in the emergence of the present-day structures of a living cell. However, can you specify the reasons for the certainty included in the statement ?
From a sample size of one instance, in a universe of perhaps infinite diversity (in infinite combinations), there
is a correlation between the presence of water, and Earth-based life-bearing organisms. It could also be stated that at present, this instance of life is also dependent on that liquid water, in order to carry out basic life functions. (No arguments there).
But until an overall causative mechanism for life is clearly established (including the sub-role water plays in it), or an instance of exo-life is verified, that's about as far as one can go .. even in speculative discussions.
Cheers
