comment Invariants of groups that are invariant under passage to finite index subgroups
Just a small comment: there's no model category structure on the category of finitely generated groups. A model structure always requires the category to have all limits and colimits.

comment Fundamental group of the moduli stack of ordinary generalized elliptic curves
Is it easy to see that the cover obtained by taking roots of (a linear fractional transformation of) the $j$-invariant is not already split by the Igusa tower?

comment Finite spectrum annihilated by multiplication by two
Is associativity necessary? It seems to me that this argument shows that any ring spectrum (up to homotopy, and not necessarily associative) with $2 = 0$ cannot be a finite spectrum (which is a more general version of the statement that the mod $2$ Moore spectrum fails to be a ring spectrum).
