Understand two things:
1. Nobody hordes till they die (and if they do, they probably needed to die)
2. The market adapts because people adapt
There is nothing stopping you from spending Bitcoin, except in the case of things you really don't want or need which sounds like more of a solution to me than anything. Is Bitcoin bad for a debt-based economy? Absolutely! Does anyone really like our debt-based economy? Only the few who don't work for a living.
1. that still doesn't lead anyone with knowledge to think that BTC will be the standard world currency. of course people are spending their BTC, but if the world economy is doing well.. people will have to invest. and BTC's inherent deflationary nature means that there'd be less people willing to invest; so how could people switch over to BTC as the standard currency?
2. how does this really prove anything? that's just a broad statement.
people are and will be spending bitcoin, and i never argued against that.. but you need to have a healthy level of encouragement to "spend" in order to keep the economy going.
