Very few of these are actually recovered. The majority are lost forever and we should not give much importance to that. While they are not recovered we have to consider them as sold at zero price and hence they make the total pool of available bitcoin lower and hence raise the price. But I agree that Bitcoin itself is rare and not much liquid even today and hence it's price is high. We should focus on increasing the amount of Bitcoin that we own and leave out the rest.

Also keeping the coins safe is an important thing as well. Don't lose your one coins thats the main thing.
