Assuming 'Siphon' is some special thingee that transcends some parts (at least) of the multiverse (Elizabeth by passing thru Tears to meddle does that type of thing in some way) then it could account for  some parts of what we saw in different 'realities'.

I wouldnt make anything absolute (as in 'immune') as the tower  (and siphon?) was destroyed in one reality  (or was it? only the external manifestation of it?  and its still somewhere, just not linked to the thing in that spot in Columbia?).

What is the actually link between Elizabeth and the thing previously called 'the Siphon'? We can spin it all different ways - She is a manifestation of it or was caused by it (its the power, bnot her), or vice versa. Even every action of the Luteces could be the same something - which happened because of this 'thing' -- just varying because of the 'fractal turbulence of the continuum' (heh buzzwords they missed...).

Is the siphon just one of an infinite similar parts of a cosmic maninfold? (etc etc at some point alot of player just say "OK enuf with this confusing BS, lets get back to the shooting").

Another 'simple' explanation is that in the 'reality' where there was no local Elizabeth (but where Monument Island WAS seen as destroyed), someone else could have taken  her place/role  and resulted in a similar outcome (the infinite multiverse says every possible combination DOES exist..... go to another one and the whole place is made of gingerbread.... and in infinite number of others you would see anything elseyou want  in the spot). Any number of realities could have generated that exact scene, but had nothing  to do with any Elizabeth/Booker/Comstock/baptism/Fink/etc etc etc...
