I fundamentally agree. If every standard put towards regional fleet growth or capability enhancement is measured in regards to high end conflict against a much larger aggressor and then ruled out as useless, what then is the point of any sort of defence force?Of course those OPV will not matter much against PLAN if games stages got 'hot' in SCS. However if PN have them and willing to used them to shown presence against Chinese vessels (like Vietnam did with mostly less capable vessels), it will provide venue from Chinese to potential change the approach to Philipines in SCS. That's a game changer in my book.
Reality says by theory of deterrence that things like presence do in fact change the calculations for a would be aggressor, as long as they maintain a logical mindset that is. If it increases potential awareness and/or opposition to an aggressive advance, any logical adversary has to build that in to their cost/gain equation.
