That's right! The beauty of Bitcoin's capped supply is that lost coins result in a decrease in the total circulating supply, which can make each remaining coin more valuable.
This concept is often misunderstood, but it's an integral part of what makes the Bitcoin network so unique and powerful. In a sense, those who lose their keys are making an inadvertent donation to the rest of the community by increasing scarcity.
While I'm sure nobody loses their coins on purpose, it does highlight how important it is to secure your private keys properly. Remember folks - not your keys, not your coins! Stay safe out there and look after your satoshis.
