There's a bit to unpack there so let's try:
Nobody makes you use a 2XP boost. It's entirely optional - you can go at your own pace even when teaming. Personally I tend to use a 50% XP boost, which still gives me inf to get started, while getting me through those first 20 levels or wherever I see the character needing to be.
I'm also spending a lot more time Redside and exploring content more which is interesting. There's a few gems there I've not encountered before, so it's a win-win and when I do team I still get a goodly amount of XP.
While I'd agree that XP boosts generally are unnecessary, I suspect we would be in the minority because people want to get to 50 fast, regardless of the fact that in my eyes at least, the journey is the destination. You only need to see the shouts in Excelsior's Pocket D for people wanting to be carried along (which I have done, but found unrewarding once I got to 50.) In other words, we're stuck with it, and must provide our own solution to that issue.
Your blindingly intense wall of text wasn't able to let me see what server you play on. Go to one with lower pop density, team, RP, play the game as intended. Find an active SG/VG on your server and join them. Just because they do it that way doesn't mean you have to be sheeple.
Play the game. Have fun with it. DXP boosts are the least of our worries in any environment.
