That Thanos cannot conceive of another solution is capitalist realism
Thanos isn't the embodiment of capitalism, he's the embodiment of Hitlerism. An ideology so intrinsically evil that the protagonists are justified in doing literally anything (including their own mini-genocides, desecrations, and nightmare science projects) to stop him.
Capitalism is embodied by the character of Tony Stark, the billionaire arms dealer ubermensch who becomes the Epic Martyr who we are expected to venerate forever. Stark's martyrdom complex echoes through the show pretty much from the beginning. Whether he's sacrificing his fortune to do Super-Charity or sacrificing his love life to do Super-Adventuring or sacrificing his physical body to do Super-Nuclear-Bomb-Throwing or sacrificing his property to stop The Scary Foreign Terrorists or finally throwing away his life to save reality itself, he is the embodiment of capitalism - the Bourgeoise Messiah who Died So That Capitalism Can Live.
The Marvel Cinematic Universe is a hagiography for the financial elites. Of course it's not going to present you with an alternative to capitalism. It's salvation is rooted in Capitalism.
