I always say faucets are great things for crypto newbies. Using faucets, they can learn basic things about how cryptocurrencies work. A few years ago, I recommend faucets to few of my friends and they learned the basics through it. What is crypt address, private key, how to follow transactions, check balance etc...
Also, we never know what it will be with (Ethereum in this case) price. Small amount today, can worth much more after year or two.
Strongly agree with the opinion you give, because many of the newcomers do not know much about the basics about the world of cryptocurrency, and the faucet is an appropriate step for newbie to move to the next stage.
