That being said, I think there is a general bias in American culture towards "making something of yourself", which results in the act of participating in non-productive activities (ex: "mindless tv" such as gameshows, infomercials) as something which you need an excuse to do. For example: "I need to de-stress so I can be productive tomorrow". When you get old, this excuse is no longer possible. Which is why folks refer to vegetating like this as "sad".

A hedonistic/utilitarian framework is a better model to look at these situations. Is that elderly individual enjoying themselves? Yes. Will their inaction today result in negative consequences (financial, health, etc.) later in life? No. In this framework, it's a perfectly good use of their time then.

As a redneck, I love America. But I think this question posed by the OP is interesting because it shows the tradeoff everyone must make in American culture between exercising individual freedoms and increasing social credit/value/standing.
