it doesn’t make sense to discuss the context itself in that way.
As I think of it, it does make sense to talk about the wider context of the rules, which are the meta-rules, but it does not make sense to demand a context that cannot itself be described within a wider context.
(If a (meta-[meta-{meta-...}])ruleset had a horizontal slice of the meta-tower identical to the other immediately higher and lower slices, then it would provide its own context. Somehow the rules and meta-rules would have to be identical, but it would still have a context, it just wouldn’t be a different context. I’m not sure this is possible, but that “possible” world isn’t ours anyway. If it were, the rules would be the meta-rules too, and we wouldn’t have to look deeper.
I strongly doubt the tower can repeat, e.g. with rules identical to meta-meta-rules, unless they are also equal to the meta-rules and every other level.
The “tower” with rules on the bottom, meta-rules above that, etc. is either repeating or non-repeating, but I don’t see how it could have a limited number of floors.)
Regardless, if the rules/first floor is empty (i.e. there are no rules by which anything exists) then the meta-rules/second floor has an occupant (i.e. “there are no rules by which anything exists”) so the meta-tower isn’t empty.
