The word 'hoarding' demonizes 'saving,' which in most Keynesian economies is considered leakage. It's really a question of values. Inflationary currencies encourage consumption; deflationary ones encourage savings. High consumption does increase demand, and apparently a faster growth in the economy. One could argue that this almost forced consumption for the sake of faster economic growth is what causes malinvestment and the associated boom-and-bust cycles.

One could be hesitant about spending away their Bitcoin to buy a shiny new bigger TV, while they'd happily part with USD for the same expense. Former, I'd say, has a more natural alignment with our incentives to spend thoughtfully.

Also, I am not sure if everyone shares the value of eating the planet at a faster rate for employment and GDP numbers.
