Satoshi was being realistic about its own design unlike all of you small blockists who didn't had the genius to invent bitcoin. He obviously wasn't locked up in a prison of fear.
The conditions under which Satoshi himself established a block size limit, remain today.
No. The recent spam attacks prove this wrong. The limit is useless.
Yes. The recent spam attacks proved Satoshi prescient. The limit is invaluable.
Didn't you notice XT Redditard Army morale imploded after the "stress tests" not only failed to demonstrate the need for larger blocks (because appropriate fees always continued to prioritize tx accordingly), but backfired by strengthening Core's defenses (in the form of smarter wallet/pool/node software like RBF)?
In the presence of adversity, Bitcoin's fee markets simply started working like they were intended to since the Genesis Block.
Lightning Network, Sidechains, other off-(main)-chain solutions.
All of them are years away from being ready, tested and proven to be secure. None of them are acceptable solutions. Bitcoin will be forked way before that.
Off-(main)-chain solutions have been here for years. Every alt chain proves you wrong. Every off-chain exchange and service (looking at you SatoshiDice) proves you are an idiot.
SC/LN are closer than you think.
Hearn@sigint.google.mil tried to block BIP65/CLTV, only to get his sorry ass steamrolled and ban-hammered.
Progress on the code is rapid. See for yourself:
https://github.com/ElementsProject/lightning/commits/masterhttps://github.com/ElementsProject/elements/commits/alphaTeam Core has the means ($21,000,000) and motivation (fuck Hearn and the former core dev he rode in on) to ramp up development by minting dozens of new core devs.
