Value is decided by the market according to the utility of the service. I happily pay $22 per year for Pinboard to keep a few bookmarks with tags. That's also storing "tiny text files" but I could not care less. I could even implement something similar myself. And yet, I find the value it provides worth paying.
Another, more extreme example. I am part of a $5000 business program. Last week, I got a single piece of advice that I consider already paid for the entire program. The delivery was 20 minutes long. It was not even something original invented by the lecturer, but it can be found in some books. And again, I don't care. The value is in the impact, not in how the advice that was discovered or delivered.
