Lost coins are actually good for the bitcoin in general. Satoshi once said that lost coins only make everyone else's coins worth slightly more. Think of it as a donation to everyone.
So this is not a problem, there is no need for 'recreate' initiatives, because it would not be wise imo.
Around one year ago, I made a quick count and found that 21 million BTC, if they would be distributed to cover ALL the Earth wealth (241 trillions), they would be not granular enough to be used as currency.
To say it another way: a single Satoshi would be valued something like 50 or 100 $, and couldn't be used for shopping in a comfortable way.
Now, of course this is an utopian scenario, but it still is a POSSIBLE scenario, and one that we all hope will be one day reached.
Sure there's alternatives out there: Litecoin could come into play as THE alternative for everyday transactions, it also has a much higher cap, it would be the silver of cryptocurrencies, and Bitcoin could be the gold.
But still: each Bitcoin or Satoshi lost, in a scenario where all Bitcoins are used, would represent a failure when granularity is not enough.
Dang. If that were to come to pass, we would all be multi-millionaires.
