It still makes sense to be able to send 1 penny's worth through a lightning channel. If someone doesn't know how... or they're not interested then how can they evaluate Bitcoin's long-term value proposition?

It's like investing in the car, without ever driving one or learning how. Eventually Bitcoin is designed to be spent, even if it's 10 sats at a time.

And the fact that Bitcoin, proof of work, can be sent 10 sats 1 penny at a time is really incredible. No other system can do that.
