EV batteries alone could satisfy short-term grid storage demand as early as 2030

I don't, LFP batteries are quite resilient. 80% -> 20% is a usability nightmare nobody with a $50k vehicle should accept. My Ioniq (first gen) doesn't even have an LFP battery and is optimized for 100% -> 13%, maybe even 100% -> 10% (turtle mode starts at 5%). Still at 100% SOH after three years.

Way more important for battery life is the charging rate (again, LFP are more resilient there too). Which wouldn't be an issue for grid use.

I think you do. If you drove 10 miles and recharged, you wouldn't consider that a "cycle". You could do that 100k times (probably more), but no one would say the battery cycle life is 100k.

I mean I didn’t count in 0.6 cycles per discharge. My battery does 0.9-0.95 cycles usually.
