While I agree with much that you've said, I don't think a lot of Christians, or now former Christians, would agree that "taking up our crosses daily" ....
today ... is only a matter of letting go of our egos. There's just too many epistemological complications for any of us to go at being Christian in that way. Sure, I too agree that Jesus of Nazareth existed as a historical person, that He died, most likely as the New Testament writers portray that He did. But the challenge in believing all of this today is what is upsetting the apple cart for many who would have more easily decided to follow after Christ and deny themselves of the world.
Anyway, as to your own personal points in all of this, I agree with you that an alottment of suffering isn't something I particularly look forward to or wish to chase after. In fact, I don't really think that suffering for the sake of suffering is what Jesus was specifically referring to when He is reported as saying we need to daily take our crosses. It's more about denying ourselves the self-actualization that a dysfunctional, sinful World promises we can have ... and if we've metaphorically born our crosses and died to sin, then there's a lot of [sinful] things we won't be doing since, again metaphorically speaking, dead crucified people don't really "do" anything.
Of course, we see this trope reflected previous to the Gospels already in what Paul and James and Peter wrote regarding "dying to ourselves before God." [................and now I'm just preaching to the choir since I know you already know this.
