Buy up primary resources that are unlikely to devalue from climate change (such as indoor farming, solar panel factories, and housing in walkable areas that are less vulnerable to climate disaster like Dublin).

Buy up the tools by which the powerful will desperately cling to power (such as the military industrial complex, media/propaganda channels, and privatized human rights like health care).

Bribe politicians, fund authoritarian-capitalist propaganda, and organize coups to put fragile dictatorships in charge of valuable strategic/industrial resources (like lithium, rare earths, fossil fuel, uranium, etc.).
