That's not really how it works. Hoarding is the worst thing people can do for Bitcoin. If entry into the market is hard, people will lose interest and with it the Bitcoin's value will drop, causing a sell-off (a sell-off would be inevitable at that point, but to what degree is debatable).

Also, if interest is low because of hoarding, goods providers have no reason to accept Bitcoin. It needs mass distribution to become stable, and if Bitcoin isn't stable, there is no way Amazon and the likes will start accepting it. If the big providers don't accept it, then Bitcoin will never be a currency.
