@vgr One billion wouldn't go all that far- family land near my home @ us-east-1 is going for $2.8M / acre, but I'd try to preserve sensitive threatened ecosystems in Appalachia.
@vgr I suppose if all my hedonistic desires are satisfied I'd already own riverfront acreage along the Shenandoah as well as the mountainside above my cabin for hiking trails & invasive plant removal (the seeds carry, very frustrating).
@vgr If budget allowed, I'd also build a live-work center... Place that specifically supports focused work by removing distractions and providing optimal conditions and support... It'd be a high-end thing, but ideally I could use it to iterate on more automated mass solutions too
