Me neither, which is why I didn’t go that route above. However, factoring human free will into the situation tends to complexify things (which is why I had to write a rather complex exposition).
Factoring in human free will doesn’t mean God will or even can ultimately lose, but it does mean that some people may (and apparently by prophecy will) continue being obstinate about their sins into the eons of the eons. Robin and Thomas are somewhat more optimistic than I am about everyone simply choosing the rational best once various stumbling blocks are removed, although I certainly agree that removing various stumbling blocks will help.
As to why He doesn’t remove all the stumbling blocks now in this life, I take it (from metaphysical reasoning and scriptural hints) that it has something to do with teaching rebel angels a lesson which will eventually contribute to them also repenting of their sins and being saved (later if not sooner). Putting it simply, the only way they’ll be convinced is if they try their hardest to win (in many various ways) against God first; but we’re the ones who suffer as a result of God’s longsuffering love for them. Some humans will refuse to learn any other way short of that either.
Not exactly what I’m talking about; punishment is about dealing with impenitent sin, and our first human ancestors were punished (but also penitent so the punishment eventually ceased once the consequences played out). There are other ways to purify people post-mortem than by punishment, and I agree that this doesn’t necessarily mean people will immediately choose the good consequentially.
What matters most for Christian universalism, categorically (compared to other theories of salvation), is that God originally persists in acting to save all sinners from sin, until whenever He gets it done by whatever mode (or modes) best fits the situation–but that mode is always going to involve the self-sacrifice of God Himself for sinners in various ways, such as on the cross.
Ever been an unrepentant sinner who refuses to listen to good reason and justice even when you can perceive it and have no stumbling blocks in the way? (I have! So was St. Paul: “Saul, Saul, how hard it is for you, to kick against the goads!”)
Logically the only path left in that case is to make the person inconvenienced by their sins, so they’ll learn to drop them. If you’ve ever been in such a condition yourself, you’ll understand the propriety of punishment. It doesn’t have to be extreme enough to be called torture or torment, but so long as the person insists on holding to sin the inconvenience of the sin is going to increase. Otherwise God would be leaving a person satisfied in their sins.
