Is this cheap because it is terrible???

Moti,
Thanks for the heads up on post fab treatment needed for CrMo. I didn't know that.
I actually built a custom rear set 4 pt weld in Cr-Mo cage for a mk1 Rabbit (with 2.0L Passat motor) years ago. Never finished the car and the new owner redid he cage, but still good to know.

Are you sure about that? I understand that the prefabricated OMP and Sparco CrMo roll cages would be subject to extra scrutiny because, despite their FIA homologation, they use metric tubing that does not conform to the NASA CCR. But there is still an allowance for them to run at least temporarily. As for other 4130 roll cages, it's right there in the rules. Which is what I've said before: RTMFRB.
According to the NASA CCR 2016.8 Section 15.6.18 "Roll Cage Tubing Sizes"
Understood. I'm not suggesting you build a new car for NASA or SCCA competition using ERW. I've said all along: RTMFRB and you may use ERW where allowed if you prefer. My previous example of LeMons/Chump car and already sitting on a pile of ERW are a perfect example of where it might make sense.

As a Chump Car participant for the past few years, I would say most of the cars I see have been around for 3+ years. Maybe LeMons cars don't last that long, but Chump Cars do last for years (they maybe ugly, but they last).

All of your posts have been trying to justify spending a dollar to save a penny WHILE NOT HAVING A VESTED INTEREST. Keep in mind, I'm assuming that you're just a ERW enthusiast and not an ERW seller/manufacturer because in that case I take back my assertion that you don't have a vested interest.
To use the MSM as an example, you're the type of poster who says "oh man, the MSM is awesome and that's a steal at $10k! It'll easily make 200 to the wheel after once you replace literally all of things that are attached to the turbo and spend $5k on it!" versus starting with an NB1/2 for $5k and buying $5k in turbo parts.

See, that's where you're wrong. None of my posts have been trying to justify using ERW over any other option. All of my posts have been defending the use of ERW in certain circumstances where warranted as a valid option among many different options. I am the only one in this thread who has raised the counterpoint against blanket, unfounded and unreasonable statements that practically equate ERW with AIDS. Get real man. I'm not the one with any vested interests here as building roll bars/cages and racing cars isn't my business, just a hobby. I have the perspective of having been around a lot of different racing for many decades and I know that there are many different ways to build a "safe" race car. Rules compliance is the responsibility of the fabricator, vehicle owner and event participant.

Now quote the second part. Here, I'll do it for you:
ERW is cheaper! It's just as strong and safe after you spend twice as much effort/time on it to make sure that it's structurally sound! I don't understand why ERW gets such a bad rap!
Like I said earlier, for someone who has ALREADY ******' ADMITTED that DOM is the superior option, you sure are spending a hell of a lot of time defending ERW. No one has denied that ERW can be used to make safe roll structures, it's just that ERW is more likely to be used in explicitly unsafe roll structures; you're taking a rounding error and turning it into a significant digit.

they should just call it 53%

Apparently ERW is fine if you hook it together with this fancy duct tape instead of welding it.

More like the Two and Four Fifteenths Bank. But actually, It's the fifth third not five thirds and likewise, third fifth as opposed to three fifths. Technically you'd still have only 8/15ths of a bank. Sounds questionable. We should all invest.
