Build and buy media networks and hire the best investigative journalists. Back centre-left political parties worldwide and back unions and backstop strike funds until the whole world strikes like the French. Fund electrified mass transit, renewable energy and passivehouse construction and urban controlled-environment agriculture. Fund orphanages, school food programs and poverty alleviation and social justice causes.
I’d also start an eco-religion whose funding goes to a land trust that buys important and sensitive lands to return to wilderness and 50% can be lightly used by humans as national parks and 50% is forbidden for humans at all. Church of Gaia. The church would have monks who work as rangers/land defenders to enforce the holy order.
I would live a quiet simple life in a relatively modest but comfortable passive house on a permaculture farm. My “car” would be a selection of percheron horses and a small selection of carriage/wagons.
Everything is worth what it’s purchaser will, or won’t, pay for it.
