First off, if money is a consideration, running the set-up w/o any pressure release at the psi he is talking about isn't going to cause any life span altering damage if only done for a couple months or so.

Secondly I think you misunderstand what the difference is between a BOV and a CBV. the only thing different between the two is where they release the air to. I don't care how nice of a BOV you buy it will never perform as well as a quality CBV. Until you start recirculating the air.

The overall point is to keep the pressure from reaching back to the turbo. Both do this, but a CBV maintains the pressure for use, i.e. between shifts the pressure is saved so you don't have a lack of pressure once you reapply throttle.

These spikes and drops in pressure play hell on your car and a BOV only exsacerbates the problem. Even if you don't reuse the saved pressure and it just slowly dissipates it's still better for your engine.

Also, when you install the adapter for the HKS SSQ, it stops being a BOV and becomes a CBV making your point, well, pointless.

I'm not knocking you really, I'm knocking the abundance of poor information out there about what each part does. Seems to be a lack of knowledge when it comes to what a part really is and how it works.
