A vaccination requirement could result in lower apparent effectiveness; so could risk compensation. In order to determine how much risk compensation occurred, we have to determine how much the vaccination requirement lowered the effectiveness. Without that analysis, concluding that risk compensation has a big enough effect to cause or contribute significantly to negative effectiveness is premature.
I am otherwise unsure of what you are trying to get at. The unvaccinated were prevented from doing a risky activity, and the vaccinated were allowed to do the activity (with a lower risk due to their status), yes.
Well, if this is consistently applied across many events, the unvaccinated will not be allowed risky activities and the vaccinated will be allowed risky activities. Which means in practice consistently higher number of risky activities available for the vaccinated. I agree that this effect might not be significantly big and more measurements would be needed.
