You can get 24 AR-15 magazines for less than $300. My Del-Ton AR was $400 on sale. You don't need to have your entire ammo supply in clips or mags, there's no point.
You can get a whole M4 clone for less than $500 afaik, but I haven't checked recent prices. You're saying the empty magazines cost nearly as much as the rifle itself? You're also not suggesting testing the magazines beforehand, which isn't cheap either. Fully loaded & pre-tested, the ammo storage winds up costing more than the rifle in some cases. Surely there's a better way, and there is, but it's not "cool" in the gun community. It's not something promoted by known "experts", so I can expect the sort of response I get. Like I said in one of my comments, if Rambo had used a clip-fed, 50-round machine gun, there would be no debate unless I switched my argument and advocated for box magazines instead.
Clips are cool. Cooler than box mags, in my opinion. Revolvers are cool, too. Revolvers even have advantages over semi-auto pistols. But those advantages aren't enough to justify using a revolver instead of a semi-auto, just like the advantages of clips aren't enough to justify using them.
I agree clip-based rifles aren't normally viable options, but only because the Garand & SKS are the only two options. Neither rifle is awful, and in the right (non mobile) scenario they could be ideal.
However, it's possible to design and build a modern clip-based rifle with en-bloc clips, and there's no reason it couldn't hold more than 8 rounds, especially with .223 ammo. An en-bloc clip-based platform with a 20 shot capacity would easily be a viable option vs. storing 10+ loaded 30-round box magazines.
Box magazines are expensive and heavy compared to clips. Metal magazines can corrode over time. In a scarcity scenario, box magazines become extremely valuable, while box-magazine fed rifles are nigh useless without the right magazines.
Even 12-16 shots would be enough for me. The Garand was originally designed to hold 10 rounds of 7mm, but the US Army wanted .30-06. A .223 version of Garand's clip could hold maybe12 rounds and still be smaller. A bigger clip with more rounds could easily be designed, especially for .223, but .30 caliber too.
Clip fed rifle can potentially be reloaded very quickly. Besides a .223 version, some "modern" improvements on the old Garand platform could be an easy means of topping off the internal magazine with loose rounds (like on a lever action or shotgun), an easier "thumb free" way to load & charge the damn thing, loading without a clip, and possibly a way to select if the clip is ejected after the last round, or otherwise removed manually.
