Partially true, partially wrong, OP.
I think it was user Rampion who phrased it something like "the long-term holders are the ones who provide the price foundation of BTC, and the shorter-term investors - and I would add: users - are those who once in a while primarily drive the 'growth spurts' to the next price level."
I think hoarders are using
BTC as store of value (at best). But it's at their own risk. Cause it might also fail.
What I am proposing is a win-win situation. Using
BTC will only make it stronger and more spread. Ultimately, merchants will keep
BTC instead of dumping it immediately.
I don't disagree with you on that: we
need adoption (both by buyers and sellers) to grow, otherwise, it's mainly speculation.
But I added two points to that: a) holders are users as well, using btc as a store of wealth, and b) because of their reluctance to sell, their participation provides a price/market cap floor (which is useful as well).
tl;dr Use Bitcoin for transactions/e-commerce as much as possible, but let's not demonize holders either.
