I see your point and I think you have a reasonable point of view, although I don't share it because I think to have that point of view you have to make assumptions I'm not comfortable making.

I think there's a lot of variables in terms of how the timeline could progress: how Russia is able to draw on other sources (trade) for equipment, how global economic winds enable Russia to deal with its labor shortages, how deep those stockpiles really go (already Western observers have significantly underestimated them), how much materiel is needed to sustain a war of attrition (in which Russia isn't advancing), how much Russian air power plays into a future timeline and how and whether Ukraine can mitigate Russian air power starting from its current air defense deficit.

When I look at these, and other variables and unknown quantities, it's hard for me to draw out that Russia is destined/doomed to lose a war of attrition, if supply just continues a little bit longer. We've witnessed Russia adapting significantly during the war - even avoiding (so far) a general mobilization. Furthermore I can think of several more ways in which Russia could win the war with sustained sponsorship of Ukraine (that never test scalability of equipment manufacture). In short, I respect that you've got that view, just uncomfortable of making the assumptions to get there myself.
