"money (in all forms, from trade/barter to electronic bits) is unnecessary in today's abundant world" - How will I pay someone on the other side of the planet for their product which cannot be produced here in my town? How will I pay 500+ suppliers for making me a new smartphone? If we all agree that various cryptos can be exchanged for various products and services worldwide, then I don't see the problem "electronic bits" for payment.
Agorism to me, means that I do not have a leader, but at the same time I look for ways to render the existing control structures obsolete and I help to build these new systems. I hold myself accountable as you said, adding into a slavery-free system. Some people are privacy coin purists, but I believe in balance, yin/yang.. We also need transparency coins like Hive so that I can see exactly where my payments are being spent. Hope that makes my views a bit more clear :)
