I don't see any plan, but will you say the same thing when the subsidy

Yes, I forgot the link:

dwindles, and mining income seems to become uncertain? It will equally
be an economic change, which equally well will have been predictable,
and it will equally well be treatable with a hardfork to increase the
subsidy.

That is a red herring.  Nobody I know has proposed this, and I am opposed to changing that fundamental.

It is well known that the 1M limit was never intended to stay, unlike 21M coin limit etc.

1M was set high in the beginning because it is a DoS engineering limit, not an [accidental] economic policy tool.


 
But I am not against a block size increase hard fork. My talk on
segregated witness even included proposed pursuing a hard fork at a
slightly later stage.

Great!

 
But what you're arguing for is that - despite being completely
expected - blocks grew fuller, and people didn't adapt to block size
pressure and a fee market, so the Core committee now needs to kick the
can down the road, because we can't accept the risk of economic
change. That sounds very much like a bailout to me.

I am arguing for continuing what we know works.  We are 100% certain blocks-not-full-on-avg works, where a "buffer" of space exists between avg block size and hard limit.

Any other avenue is by definition speculation and risk.  You _think_ you know what a healthy fee market _should_ be.  Massive damage occurs to bitcoin if you are wrong - and I listed several 

vis expectation, there is clear consensus and expectation that block size would increase, from 2010 onward.  It was always a question of _when_ not if.

Sticking with 1M presents clear risk of (a) economic fracture and (b) community fracture.  It quite clearly risks massive change to an unknown system at an unknown, unpredictable date in the future.

BIP 102 presents an expected upgrade at a predictable date in the future.
