I love Zeus. It is fucking awesome. It is my main lightning wallet. There are technical issues and real life costs to running it.
But the first 0-100,000k sats on nostr for newbies or no coiners can be a challenge. One that is often cast aside by those with established lightning nodes and channels. The use of ecash for those circumstances makes a lot of sense in allowing cheap no kyc private ease of use.
Though we need better decentralised non costodial solution for those bellow 100,000 sat range payments
