Cash is great. So is Bitcoin in its own way. As well as ecash and Monero.
The world is complex. Some order is nice. Some chaos is necessary. You'll never create something that is a perfect fit for all under any circumstances for forever.
Once you understand this you can appreciate other shitcoins like Monero as Bitcoin itself is nothing more than a shitcoin for the time of its existence. A short blossomjng before the eternal nothingness.
