If we want crypto currency to be a currency we have to keep spending right? But at the same time it's something worth keeping too since I do the same with my fiat in bank for more than 2years without touching it. Is it possible to say that Bitcoin in every wallet for the past 2years without moving are considered lost due to death or lost recovery keys? It's pretty hard to believe that anyone won't come back for their Bitcoin after 2years with no activities on the wallet.
What makes you think that an inactive wallet is a dead wallet, even if it stays inactive for long period, I am not convinced that even Satoshi wallet will remain inactive forever since Bitcoin is developed to promote anonymity and privacy, Bitcoin is hard to be tied to an individual most especially in self custody wallet, it becomes clear how no bitcoin should be termed as dead on forever inactive and the advantage that these inactive wallets have on the networks is that it contribucontributesstability of the market movement and aid scarcity of Bitcoin as long as there remain inactive.
-That is why you hear some slogans such as, lost Bitcoin is a donation to everyone holding bitcoin, what that means is, the amount in the circulating supply will become limited and this will force the price to increase.
