Can I run 37s with a 4 inch lift?

On a 4 inch lift with no wheelbase stretch, you'll have better stability on hill climbs and more uptravel with 35's, which makes it better for rock crawling.
When you're in mud, uptravel means almost nothing, the biggest determiner is clearance at the diff/axle tube, which would make 37's worth considering.

Am I wrong?
You are not wrong as long as you nail down a bunch of "all other things being equal" type stuff. As in, toss a pre packaged long arm kit in the mix and then yes, you are wrong unless the guy with 37's has the same kit, then they both suck equally.

Totally off topic, but the roll cage bracing in that looks really clean. Nice Jeep!
Clean, practically useless as a cage though. But some folks don't want a cage, they just want to look like they have a cage and there's nothing wrong with that.

Would a JK axle swap, rubicon, be a more affordable route for someone looking to make the jump to 37s? From what I see on the trails many JK/U's are running 37s with stock axles, likely not internals, and aren't breaking.

If you were choosing between OEM JK Rubicon axles and aftermarket built axles, the JK axles would be somewhat cheaper but SHOCKINGLY costly. I texted a few people on craigslist because I was tossing around the idea of using full width JK axles (with stock JK wheels so its not too wide). The cheapest asking price for a pair of stock JK axles (non-rubicon) was $2500.
Two thousand five hundred dollars for a stock Dana 30 and Dana 44 from a totaled Jeep. So it'll still be quite expensive especially for Rubicon axles.
That being said you might be able to get some JL/JT axles for a more reasonable price as many people are buying JL/JT rubicons and putting them on tons/40s as a pavement princess rig.

As for the question of strength, they use bigger ring gears, thicker tubes. They are capable of holding locked 37s with chromoly shafts, etc. I can't speak for the ball joints on the front though.

It would really only be marginally more affordable unless you found a killer deal.
My two cents is that for less than $250 you could pick up two junkyard axles and fully build them; thats the most cost effective route.

I know this question has probably been asked a million times but can I run 37s with a 4 inch lift? I am currently running tube fenders in the rear and high lines in the front.
:oops: You can do anything you want to it. It's your Jeep.

That Jeep probably holds the record for most RTI ramps driven up.
That was the owner's intentions when she built it. She enjoys it, so why should it matter to anyone else? I met her she doesn't give a shit what anyone thinks about anything. More people should be like that and stop building their Jeeps to suit others.

Nobody cares how someone builds their Jeep, but if you ask for recommendations on how to build a Jeep on 37’s, nobody will recommend the build in your pictures. That doesn’t mean anybody cares that it is built that way. Nobody would recommend the way I built my Jeep either.
 
Whats useless about it?
No windshield bar. No triangulation in the B pillar over the seats. No harness bar. No window bar. No frame tie ins. A pillar is a bent piece of sheet metal with a very small cross section near the floor. No diagonal from top of B to bottom of C.

So it does. Got it.
No, you ain't got shit. Asking if something has "more" rather than "sufficient" means you need the ability to predict the future to ensure that you encounter vehicular displacements that will only use the protections within their limited improvements. Some is not the same as enough, not now, not ever.

Yawn.
