There are places in the world where people still use natural resources more than fiat currencies to transact. In Sub-Saharan Africa a grandmother will grow a crop of tomatoes to trade for two chickens and 40kg of rice. She will earn 1.50$ per day otherwise. It would be great for her to use e-cash to make those transactions, But a 100$ smartphone is a serious investment for an elderly woman who relies on her 8 grandchildren to help her along in life. I am just stating it is worth doing some market research to find real world use cases.

If people are still using barter, that's fine, they don't need money.
If they do need money, I'm suggesting e-cash could be converted into PHYSICAL CASH. I don't know how to be more clear, you don't seem to be reading my words. PHYSICAL CASH. PAPER BILLS. I'm not suggesting an African grandmother needs to buy a smartphone. You're the one implying that e-cash isn't worth developing because you need a smartphone to use it. I'm the one arguing you might not need a smartphone to use it.
