ASA OBS call then no call leads to ejection

What is the problem with that? As stated, it was a gapper and if the umpire believes the obstruction caused the runner to be put out prior to reaching the base s/he would have had the obstruction not occurred, then it is the correct call.

It seems too difficult to determine if the runner would have gained 4 bases had there been no OBS at 1B (gapper notwithstanding).

Q. If the umpire determines that a triple is probable and B1 decides to round and go for home only to be tagged out does B1 get the call for OBS and safe?

As a judgment situation, I am looking for a guide in determining how far do I protect the runner (specfically when OBS at 1B). Are you saying I must go all the way to the base that B1 is attempting to attain?
