Rangers will have serious financial clout in the lower divisions, it's not like being relegated to L2 where you'r eplaying against teams getting a few thousand a week, you're talking teams who get a few hundred paying fans, Gers fans will stick with the newco 100% and I'd expect a sell out most weeks home and away, they should walk it back to the SPL over the next 3 seasons as they'll be starting with a clean slate financially. They have been allowed by the SFL to sign players in this transfer window, after which they cannot sign in the next 2 I believe, sounds fair to me as you can't really leave a team with no players.
