with today's digital world, information is increasingly susceptable to corruption or loss - especially if you don't do backup.
i think there should be a system implemented where your wallet is actually stored in the cloud, inaccessible without your encryption password.
this eliminates the lost wallet problem, and can also be modified so that any unused wallets (again, a set period of say 100 years) have their bitcoin value deleted & added back into unminted blocks.
or just buy physical BTC

i just wonder - how easy would it be for somebody to do this:
buy BTC coins
open them, make photocopies of the code inside
make new "real" fake coins - they have a real code but there are copies of it - this way everything checks out & the first redeemer will get his BTC
any remaining fakes thus become worthless - but not until the owner checks up on the public block checker!
many fakes could circulate for YEARS as real currency until someone redeems one of them, rendering the rest worthless.
this type of scam could go un-noticed for a very long time - not many people are keen to redeem the coins!
