Plan of Salvation doesn't make much sense

This isn't my thought, I copied it from an anonymous reddit user but it makes a lot of sense to me:

Right, and usually when I bring this up, believers will quickly bring up temple work, but that doesn't really address the issue I'm speaking to. Yes, I understand that temple work is supposed to save the uninitiated. The problem is that when 99.9999% (estimating 21 million members since 1830, and 107 billion people ever) of humanity will be saved for their actions taken in the spirit world, the entire point of earth life in the Plan of Salvation becomes pointless. We say it's the time to prepare to meet God, but it isn't for the vast majority of humans who have ever lived. It's pointless suffering and violence that accomplishes nothing more than gaining an earth body. As a means to acquire a body, it's a bit overengineered on God's part, and probably redundant considering it doesn't even give us the resurrected body we really care about. God can apparently just summon that into existence, so what's the point of getting an inferior body here first? So the Plan of Salvation purports to explain the purpose of life, but if you pick at it very long, you realize it doesn't explain anything really. For a precious few people, earth life will actually fulfill its stated purpose. For everyone else, it's pointless. And of course, when you consider the centuries and millennia that have passed for entire civilizations and races to whom God neglected to impart ordinances or the gospel, it becomes really difficult to believe that my and others' salvation depends on doing home teaching, attending all my meetings and not drinking coffee.
