Personally I like tradition. And while there's always a risk with a natural cork, there's nothing comparable than the ritual of opening a nice botle of wine with such a cork.
However, experiencing a wine that was badly corked or tainted by TCA never is a cheerful experience.
Whenever a customer experiences such an issue (happened 4 times only, twice with the same winery but different wines, more on that further on) I always replace the bottle, knowing also that the winery will give me a compensation (I'd replace it anyway of course). Here's the story: Some (very famous) winery I'd rather not name here (you'd be undoubtedly shocked and surprised!) wouldn't even accept the idea that their quite pricey wine could be affected by TCA or badly handled cork-wise, acting with such pretension and arrogance as if their wines were above the others in a way that they'd be immunized from such occurrence and thus refused to replace the bottle.

I was so furious that I called up the winemaker/owner and threatened them in a way that calmed him down quite a bit.
However I wonder if such issue would occur with a super premium wine for an older yet still alive vintage if the winery would "wine up" and take responsibility. While I would always advise and explain the risk, most people don't take into consideration the risk they are taking when buying a bottle like that and would be likely not willing to assume their own responsibility in case the bottle they purchased at a significant cost went belly up due to a cork issue or simply because the wine was past its peak.
Tradition and risks...
Best,
