Is the value of websites indistinguishable from a bunch of batteries just because its form can't be meaningfully distinguished from a battery to a drunk 12th century techno illiterate in a tavern?
To explain what a bitcoin actually is to people utterly ignorant and skeptical of how information stored on hardware works sounds like an exercise that can be left to the writer, they may have to spend the rest or their lives explaining every bit of tech to every layman.
What is a book after all? Dead trees stained with ink? What intrinsic value does that hold? If someone were to ask stubbornly the value of any book, I'd be similarly disinclined to spend the time explaining that as well.
Like with TVs and cell phones and plumbing, lay people will stop asking or caring about "What is bitcoin" once you can give a functional answer of "You can buy a house with it". Explaining what it actually is to people that obtuse will not get one any closer to that point anyway, so I'm not sure what the value is.
The cycle for the next wave of technology whose final purpose and form baffles the general public will continue on and on, this is just a season we're in, like all the ones before.
