I think the biggest thing holding people back from spending their bitcoins, is the possibility that the value of these coins might drastically increase in value and that those purchases might come back to haunt them. <Like the Lazlo Pizza>
I just want to flip this into the opposite of this scenario and just imagine that you did not spend those coins and it goes down to $1000. How will you feel then? I would much rather spend some coins and have something to show for it, than not spending it and sitting with some low value coins in the end.
Take the 80/20 spending strategy, if you want to be cautious, which is spending 20% and hoarding 80% of your coins.

yes, and that is why some people let their coins hoard up to very much, and if they are lucky, they will get a lot of profits from the coins they tube.
but as explained above, the worst case scenario is that the price of coins does not always rise.
so, it's wise to spend part and save some. distribution strategies can be freely arranged as desired. but for me, more to save is better.
