This is precisely the sort of cheerful thinking that philosophers are paid to provide and all kudos to Sartre for coming up with it. But I think quite differently about Sartre and the Myth of Sisyphus having just seen that Simone de Beauvoir wrote: "Few tasks are more like the torture of Sisyphus than housework, with its endless repetition: the clean becomes soiled, the soiled is made clean, over and over, day after day. The housewife wears herself out marking time: she makes nothing, simply perpetuates the present." (That's from The Second Sex.)
The Sartre-de Beauvoir household was an unconventional one. Perhaps one manifestation of this was that a private argument between them was thrashed out through some of the major philosophical works of the 20th century. Is it too fanciful (as a philosopher might say, at least on the other side of the Channel) to read that passage in the Second Sex as Simone saying to Jean-Paul: "if you want to embrace the fundamental absurdity of human existence then you can start by doing the dishes"?
