First thing to do is look at that KJV word "prevent" in the Greek, because it's not the word 'prevent', but in the Greek means 'precede'. I don't know why the KJV translators brought that into English as "prevent"...we say unto you by the word of the Lord, that we which are alive and remain unto the coming of the Lord shall not prevent them which are asleep.
NT:5348
phthano (fthan'-o); apparently a primary verb; to be beforehand, i.e. anticipate or precede; by extension, to have arrived at:
KJV - (already) attain, come, prevent.

Paul is simply saying with that, that we who remain and are still alive shall not 'precede' the asleep saints that are already there with Jesus (per 2 Cor.5, remember?).
Yeah, you're right, I cannot agree with all your 'personal' correlations you're trying to make in the above.I get you will disagree. But to me the following 1 Corinthians 11:26-34 discerning of the Lord’s body; speaks of not preventing those weak and sickly among you from eating that they may be strengthened in Christ…but instead those hungry and thirsty are pushed out of the way and there are those who eat unto drunkenness and those who go away from the Lords table hungry. “You do show the Lord’d death until He comes”? No? Many there are among you who are weak and sickly and do sleep. He told the Pharisees not only do they not enter but the prevent others trying to “awake, awake, wake up unto righteousness and the Lord will give you Light” but instead they feared, “all will believe on this Son of God -and it will take away our positions and status as high men!” There is still a “not discerning the Lord’s body today” saying “we have Jesus” “come and see” but wait for the response… “did you actually think I cared about you state or well being? Well I don’t.” Yet those strong ought not prevent those who weak, but instead the strong ought to support the weak. Or those that have fallen asleep. Romans 13:11-12 Besides this you know the time, that the hour has come for you to wake from sleep. For salvation is nearer to us now than when we first believed. [12] The night is far gone; the day is at hand. So then let us cast off the works of darkness and put on the armor of light.
It's like your thoughts are all over the place because you are trying to tie simple words together from different Scriptures. We must always remain within the 'context' of the verse's subject regardless, and you really are not doing that.
The 1 Corinthians 11:26-34 Scripture is about those who were treating Communion with Christ like a Church social dinner. They were keeping it in an 'unworthily' manner. Instead, we are to 'examine' ourselves when keeping it, like Paul said there. It's supposed to be an event when we judge ourselves, i.e., work out things with Jesus in communion with Him, and especially for remembering what He did for us on His cross. This is why the Christian Church represents that with a Communion service in quietness, and in a respective manner. To treat it like a Church social dinner is not how to treat Communion with Christ Jesus.
So I fail to grasp how you are trying to relate that to what Jesus said to the Pharisees, just because of that word "prevent", which actually isn't even in the Greek of 1 Thess.4:15 anyway.
