Re: The Barry Silbert segwit2x agreement with >80% miner support.
...This needs to be stopped and making 1 MB the minimum size is a good step in ensuring that.
There it is, the dumbest thing I've read in 59 pages. 
Q: And what happens when there isn't 1MB worth of segwit transactions?
A: 1 hour block times.
Well, I don't see why a miner wouldn't fill up the block to 1 MB with dummy transactions, just to not waste his hash rate, and get the next block while all others are waiting to start to mine until they can fill up a 1 MB block...
A lower limit on block size will never be a problem, because miners can make blocks as large as they want with own dummy transactions. This makes that miners cannot play games with small blocks as they are now not part of the protocol any more, and all "relative network advantage" between 1 MB and 2 MB is much smaller than between 10 KB and 1 MB.
