1) It is theft. The "lost coins" (including not so lost ones) don't belong to you.
2) It is changing the rules after the fact. If Bitcoin implemented this from day 1 it would be not quite as bad but there is a "social contract" in Bitcoin. Here are the rules, the system is volentary, if you don't like them you don't need to use them. Changing the rules after the fact is a bait and switch.
3) This has been proposed at least a hundred times by a hundred different people going as far back at 2010.
4) It won't happen. I am not saying it won't happen because it is a bad idea it simply won't happen. Bitcoin requires consensus. Any break from the consensus is a hard fork. The existing "no coin theft" Bitcoin will still exist. You can't force it to stop. The bad news is two different completely incompatible bitcoins both calling themselves "bitcoin" is just a recipe for mass chaos and confusion. The utility value of both systems declines.
5) If you want to steal coins then make a new crypto-currency, call it "steal-a-coin" or something and see how popular it is.
1) Is it theft when an unclaimed estate is handed over to the state?
2) Technically the rules of bitcoin have already changed after the fact if you were watching the recent fork and changes to client.
3) Sorry I guess I did not look hard enough! My bad.
4) I agree it is unlikely but not impossible. The mining community recently had to come to consensus on the issue of the large blocks breaking older clients. As cryptography progresses it is likely the protocol will have to adopt a new encryption algorithm eventually etc etc.
5) HA. HA. HA. What you call stealing, I call recycling. I honestly think there is a slight chance that lost coins could become an issue in the extremely long term. It's just a matter of fact that coins will continue to be lost shrinking the supply from the intended 21 million.
Some how, some way, we need to teach every noob how to use the search function. Maybe they should all have to prove they know how to search for a topic before they get out of noob jail?
Moderators, can we make this happen? Just some sort of test where they have to use the search function once before they are allowed to post "new" topics?
Sorry to be "that guy". I honestly did search but didn't find anything. If you're not too busy hate'n could you point me in the right direction?
