Correct - if by "we" you mean the user that are not miners with a boatload of hashing power.  Nothing you say matters.  Nothing I say matters.  Nothing Carlton says matters.  Nothing said here on bitcointalk.org or reddit matters.  The decision will be made by the miners.  If they all agree that raising the block size will make them more money - they will do it (they won't).  If they all agree Segwit will make them more money - they will do it (they won't).  If they all agree changing the PoW algorithm will make them more money - the will do it (it will not, they won't)

Your choice.
