Yes, there is great potential here - as it offers to "scale" the fee problem as well as txn scaling...

1. Pleb signs up for some custodian account (ie. Coinbase, etc) - gets "eCash". Pays 0 fees.
2. Transacts and does things....eventually as reserve builds up pulls off some via LN to self-custody wallet....pays minimal fee
3. As LN reserve builds up further, eventually transfers "savings" into onchain self-custody solution....pays high fees but total control
