Have you considered that Bitcoin users like me will simply refuse such "fixes". I will either fork the block chain with others like me, or I will sell all my Bitcoins and move on to the next money system that doesn't rob me of value.

Technology will find ways to reduce the amount of lost coins. Safety features, automatic wallet ownership transfers upon account inactivity (death), etc. You are making a mountain out of a molehill.

Since when does being born entitle you to money?

Suggesting that no one will invest in a deflationary economy is ludicrous. What it will do is drive off malinvestment. Good ideas will remain hugely profitable.

Hoarding is temporary. Not many people can enjoy staring at a fat Bitcoin wallet. People enjoy things like life, vacations, toys, fast cars, boats, planes, guns, food, alcohol, houses, land, automatic flushing toilets, a toaster that knows when you wake up, exotic animals roaming the courtyard, replacing body parts with mechanical representations, etc. etc. etc.

If you can design a block chain with rules that are more desirable, please, feel free. Let it compete with the current implementation and the more desirable block chain will rise to the top. Perhaps, because there are so many people that want their money to lose value over time, both chains will coexist! I couldn't imagine a more perfect world! Then the people who love inflation will leave this block chain alone. You can all sit around and watch your money lose value together!
