In order to get the ecash, you need to send an onchain transaction to open a lightning channel, pay onchain fees, then send btc to the mint on lightning, pay fees on that again, then you get the ecash which needs to be withdrawn later - all that for $5?
Whats the use case for buying something with ecash for $5?
no, you dont id you cant afford: you can buy with fiat or exchange some other resources or wokr directly for ecash, like you can use $ without depositing gold in a bank.
Then, when you exceed the amount that is ok to have in a bank you can buy a some liquidity for a non-custodial channel by some provider and start your stack. If, at some point, you will reach an amout that have sense to detain in a on-chain utxo, you can swap.
Today bitcoiners joined ecash by the path:
on-chain ----> lightning ----> ecash
but in the future the path would be probably the opposite, and I think would be a good way to scale bitcoin adoption, with ecash neo-banks replacing old banks.
