"Traditional values" usually means conservatism, ie. maintaining the status quo, whatever that happens to be.
There can be value in resisting change, because change can have negative consequences. There can be value in conservatism, because it helps prevent the progressives in society from enacting change too rapidly and destabilizing core systems.
Not that I disagree with what you are saying...I guess I want to refine it?
I hold with Corey Robin's general thesis, that the status quo is inherently reactionary, but Conservatism, as an outgrowth and co-option of liberal political processes in defence of the Ancien Regime, is actually dynamic. One of the greatest conservative political thinkers, Joseph de Maistre, posted a brilliant defence of absolutist monarchy...which is a shame, because France was never an absolutist monarchy (Machiavelli neatly disposes of that lie in The Prince).
Which pretty much sums up Conservatism all over. It creates an imagined better past, to denigrate the present. That past usually never existed, as those who operated as part of the status quo in the past were normally more heterogenerous in their views and attitudes than conservative theorists allow for.
This isn't entirely unsurprising, as the British political philosopher John Gray noted the same problem in how the concept of the "free market" was approached, a good few years before Robin wrote his thesis on conservatism (I'd love to see them sit down and discuss their respective books together). The actual theorists of the free market were far more complicated and nuanced in their thought than their modern disciples...which is no surprise to anyone who has actually read Adam Smith.
And I agree, there is some value in conservatism. Shaking up the core processes of society in a fast and haphazard manner is probably going to have negative consequences, because shit is complicated. The French and the Russians tried that complete overhaul method, and well it didn't turn out too great. Of course, all governments impact on their society, even the ones which claim they don't, but it's a matter of degrees, methods and implementation. Gay marriage isn't going to ruin civilization...but putting farmers in charge of factories and factory workers in charge of farms might create an industrial recession and famine, leading to greater social unrest which spurs on political violence both by the regime and those who oppose it. For example.
