That's fine for the people who are into that collectable stuff..but for the "average" DM who needs an X mini, this just...well..sucks.
There are two aspects here:
First, if you use miniatures, you like to have miniatures that correspond to the monsters you're using - a possible result of that is that the monsters you use are determined by the miniatures you possess.
Thus, a random selection of miniatures expands the range of monsters available in the game!
Second, you must consider the popularity of the "X" mini. With an orc miniature, with a common rarity, you'll have a lot of them available (and very cheaply on the secondary market as well!)
With the Drappled Yograt of Thun miniature (a rare, unique monster), only one or two DMs are going to want it. If it were sold singly, either it wouldn't be produced, or a high price would be attached to it due to the limited usefulness - in this case, the Collectable aspect serves it well, permitting it to be made.
The one aspect where collectability is not good is when a popular miniature is made rare for no good reason. (For instance, if Ogres were made rare). I hope they keep this to a minimum.
Cheers!
