It.. was enough for NASA to accept the proposal? I don't really understand your point.
also, I don't expect suits to provide any protection from ionizing radiation, I don't think it's possible to meet both mobility and shielding requirements; the physics don't allow it
The same suits you referenced do, in fact, provide a decent amount of protection from ionizing radiation. Is it "enough"? Enough for what? A couple hours in open space? A week sleeping in the suit in orbit? Clearly the ones you referenced provide enough protection for Moonwalks.
As I quoted a moment ago, you asserted that physics don't allow it. Clearly they do. That's all. Street-Conclusion-99 even mentioned Unobtanium happily being able to bridge the gap, so physics wasn't even really part of the conversation to begin with.
Not to ruin a good Reddit argument with fun world building, but another option would be generated magnetic fields. Saves a lot of bulk from being needed to fully shielded from radiation, the issue being energy expenditure. A long distance space vessel could use this, and the protection will extend a small radius outside the ship as well
It’s also worth noting that the suit seems primarily designed to be an IVA suit, with occasional outside work (for hopefully short periods). Even current technology IVA suits fit the profile of the suit in the image, but tend to be cumbersome when pressurized and not suitable for long term intense usage, as described

Pretty solid tissue paper.
For reference, the ISS sees about 30x the radiation of the surface according to the ESA.
