I am very happy to hear people discuss this topic. When I found out about the Lightning Network, my first idea was that this allows free sat transfers for those who want.

One thing I still dislike is that there is no channel type which will be stable, i.e. where a force-close would not be possible but any close would require two humans agreeing and cooperating (not just bots signing something according to the protocol). But this part is easily worked around with 2of2 multi-sig wallets (which can exist as another long-term and zero-fee way to settle while the same two parties have a LN channel with zero fees).

But really very happy there is a growing number of those asking this question. All the best!
