Changes in bitcoin are possible and happen. For example, if we want to have more divisibility, we have to change the protocol.
To allow more complex transactions, the protocol is going to be changed soon.
those kind of changes don't do any harm to my money,
yours would.
and i gave you a few examples how it can hurt me.
if i'm a non-techie person and want to "hoard" my coins offline, using BitBills for example, you want me to destroy them after X years (and import the BTCs to an online wallet), just to not lose my coins.
i bought those BitBills for a reason, i paid for those coins, it's up to me what todo with them.
no protocol-changes ever should change that, or at least should be on their own fork (maybe i would use that fork too, by choice, not forced to).
This is a misunderstanding of a social experiment. If the greater good deems it necessary to tear down your house to build a Walmart, then that is the price of living in a social experiment of laws. There are many investment vehicles for long term storage of value that you may use that will not cost me electricity, such as stock, gold and real estate, but then you will bear the cost of maintaining them. Bear in mind, that any changes to bitcoin will require very good reasons, and that is one reason why we have a forum.
