We know perfectly well that the system will need to eventually be
sustained by fees.
We should stop misinforming new users talking them about how bitcoin
transactions "are free", because they're clearly not.

Am I "artificially manipulating expectations" ?

Timestamping data using the blockchain is not the same as including
that the data in the blockchain itself because the later is a scarce
resource.
The "timestamping space" is already unlimited today with no changes.
You can use a bitcoin transaction to timestamp an unbounded amount of
external data using exactly 0 extra bytes in your transaction!
Here's the code: https://github.com/Blockstream/contracthashtool

And I'm very interested in scaling Bitcoin, I just disagree that
changing a constant is a "scaling solution".

I extremely disagree that having a block limit is failure. It's a
design decision to protect the system against centralization (which we
will be able to rise as we solve technical and centralization problems
we have today).
But thank you for being more clear about it now, Gavin. You won't stop
on a 8GB or 32GB limit because you think having ANY limit would be a
failure.
Is that correct?
If not, can you please answer clearly when and why you think the
blocksize should be lower than demand (when you will be ok with
bitcoin users having to pay fees for the service they're enjoying)?
If your answer is "never", I would prefer to hear it from you than
just concluding it by the lack of an answer.
