The problem is that Intel is already more than 2 technology nodes behind. Catching up could be exponentially expensive, especially if all orders are now going to Taiwan.
Intel 10mm is approximately like TSMC 7mm (different measurements but similar transistor density). So I'd say 1.5 nodes behind? AMD and TSMC used to be behind like that, and eventually they caught up. Intel has the resources, and given shortages, they have a bit of time too.
Since 20nm, a node step does not necessarily have anything to do with sizes and is purely a marketing term. Even if there are size shrinks, they are hardly comparable if a switch to another technology (FinFET -> GAAT) is involved as well.
