I'm not seeing anywhere in that page anything about an assumed static basket of human wants and needs. Maybe I missed it -- can you point out where you saw that?
Interesting, though, that per the very same article someone like Adam Smith concurred empirically with Marx's observation on the titular tendency of rates of profit to fall. This suggests to me it likely had some meat to it.
Without going too deep on it (I used to be a fan in university as a silly youth), the tendency of the rate of profit to fall is the key aspect of Marx's crisis theory.
Basically dude thought the competition inherent in capitalism would cause all profit to be competed to zero leading to an eventual 'crisis' and collapse of the capitalist means of production.
Implicit in this assumption is the idea that the things humans need and want changes/evolves in a predictable way, and not in a chaotic/fractal/reflexive way (which is what actually happens).
An eventual static basket of desired goods would be the only mechanism by which competition ever could compete profits to zero. If the basket is dynamic/reflexive/evolving, there's constantly new gaps opening between human desires and market offerings to arbitrage for profit. You can just look at the average profit margins of S&P500 companies over time to see they are not falling.
The further we get from subsistence worries (Adam Smith's invisible hand has pulled virtually the entire globe out of living in the dirt), the more divergent and higher abstraction these wants and needs become, and hence the profit opportunities are only increasing -- which is how the economy grows (no, it's not a fixed pie, another Marxian fallacy).
