Not so "automatically". The reason why the devs like soft forks is that they can deploy the protocol changes without having to alert everybody to upgrade (and therefore to explain *why* the change is good for them).
Are you insinuating that SW isn't good for them? They will eventually change as most users do update their wallets regularly and this has 100% consensus with devs.
What I meant is that big junk generating businesses can upgrade to exploit SW immediately, while the majority of the occasional clients will take months to do so.
Users can decide to immediately use bitcoin core or wallets that have the upgrade if they want. You are assuming that we are already at 100% capacity and SatoshiDice is going to rush in to exploit the extra bandwidth. We aren't using our capacity now, what makes you think that building bigger capacity will insure that it immediately gets filled?
Its a bit odd that you are both so skeptical of bitcoin but so optimistic at the same time expecting huge growth in usage and tx's(whether you think those tx are legitimate or not is inconsequential as it represents growth in the ecosystem). Or perhaps you are hoping that blockstream and core fails to deliver scalable capacity improvements and bitcoin bloats from spam so it becomes technically unusable? This would explain a lot of your vitriol for them.
Phew, for a moment I was afraid that Blockstream had relented and proposed SW as a way to increase the capacity and avoid congestion. But with users inertia and a bit of help from junk generators, the "fee market" may still begin in six months or so.
So everything is back to the status quo in diebus bello, and the Bitcoin Stalling Conference had the outcome that everybody expected.

SW is indeed a piece of the puzzle to increase capacity along with the list of changes that are being outlined in the provided link that you appear to have ignored. ETA for SW moving over from sidechain testnet to main bitcoin testnet this month and deployment in late 15 or jan 16'
Why are you so interested in Bitcoin's well being and against the "fee market"? Why not be an impartial academic observer and watch as these events unfold? Do you have some sort of stake in large blocks being the primary means of growing capacity vs these more holistic approaches that take into consideration many variables ?
I suppose you could have been watching this drama for so long that you have built a natural preference for certain "teams" and irrationally invest in an outcome you have no stake in. Happens all the time with sports fanatics. Is this the case with you?
