And investors accept it because they understand distribution is necessary to gain adoption and make it worth something via Metcalf's Law.

Coins that stop distribution die (Bitcoin will either die or be morphed with debasement when the G20 government coordination takes it over via the 1 or 2 pools that control it). Gold with its very low rate of distribution has never been used a currency (without additional debasement), not even in Byzantine.

The reason is very simple and due to the power law distribution of money[1]. Investors don't redistribute to spenders because they only spend a small fraction of their net worth. Thus government must step in and redistribute it. Crypto-currency offers the option of decentralized redistribution (that can't be gamed by the power vacuum of democracy). That is the reason I would prefer to go to 5% than 3%, but the investors here are ignorant. That is why I am teaching now.

Naive investors don't understand that there is a symbiosis between investing and spending, you can't have one without the other. Warren Buffet understands this.

Btw, Monero appears to have a very serious fatal flaw (another reason I didn't bother to develop for it, nor buy it). With the distribution rate being so high, it is impossible to bring it down without causing the miners to leave for another coin[2]. If I designed a currency, never would I make the initial distribution so much higher than the long-term. (do you really believe the core developers are so unselfish as they try to paint themselves, of course not!...why did they set the initial debasement rate so high...to get more coins!)
