I'm mainly just an observer on this. I mostly agree with Pieter. Also, I think the main reason why people like Gavin and Mike Hearn are trying to rush this through is because they have some kind of "apps" that depend on zero conf instant transactions, so this would of course require more traffic on the blockchain. I think people like Gavin or Mike should state clearly what kind of (rigorous) system for instant transactions is satisfactory for use in their applications. Be it lightning or something similar, what is good enough? And no zero conf is not a real secure system. Then once we know what is good enough for them (and everyone else), we can implement it as a soft fork into the protocol, and it's a win win situation for both sides (we can also benefit from all the new users people like Mike are trying bring in).

Can you please elaborate on what terrible things will happen if we
don't increase the block size by winter this year?
I assume that you are expecting full blocks by then, have you used any
statistical technique to come up with that date or is it just your
guess?
Because I love wild guesses and mine is that full 1 MB blocks will not
happen until June 2017.

We've successfully reached consensus for several softfork proposals already.
I agree with others that hardfork need to be uncontroversial and there
should be consensus about them.
If you have other ideas for the criteria for hardfork deployment all I'm ears.
I just hope that by  "What we need to see right now is leadership" you
don't mean something like "when Gaving and Mike agree it's enough to
deploy a hardfork" when you go from vague to concrete.

Oh, so your answer to "bitcoin will eventually need to live on fees
and we would like to know more about how it will look like then" it's
"no bitcoin long term it's broken long term but that's far away in the
future so let's just worry about the present".
I agree that it's hard to predict that future, but having some
competition for block space would actually help us get more data on a
similar situation to be able to predict that future better.
What you want to avoid at all cost (the block size actually being
used), I see as the best opportunity we have to look into the future.

Free transactions are a gift from miners that run an altruistic policy.
That's great but we shouldn't rely on them for the future. They will
likely disappear at some point and that's ok.
In any case, he's not complaining about the lack of free transactions,
more like the opposite.
He is saying that's very easy to get free transactions in the next
block and blocks aren't full so there's no incentive to include fees
to compete for the space.
We can talk a lot about "a fee market" and build a theoretically
perfect fee estimator but we won't actually have a fee market until
there's some competition for space.
Nobody will pay for space that's abundant just like people don't pay
for the air they breath.

Ok, this is my plan: we wait 12 months, hope that your estimations are
correct (in case that my guess was better than yours, we keep waiting
until June 2017) and start having full blocks and people having to
wait 2 blocks for their transactions to be confirmed some times.
That would be the beginning of a true "fee market", something that
Gavin used to say was his #1 priority not so long ago (which seems
contradictory with his current efforts to avoid that from happening).
Having a true fee market seems clearly an advantage.
What are supposedly disastrous negative parts of this plan that make
an alternative plan (ie: increasing the block size) so necessary and
obvious.
I think the advocates of the size increase are failing to explain the
disadvantages of maintaining the current size. It feels like the
explanation are missing because it should be somehow obvious how the
sky will burn if we don't increase the block size soon.
But, well, it is not obvious to me, so please elaborate on why having
a fee market (instead of just an price estimator for a market that
doesn't even really exist) would be a disaster.
