ubi> we arent oiver even a D’rabanan to prevent someone else’s issur.
thanks for explaining the teshuva. I agree that my argument about shofar is an agadta, we can’t just apply it to any issur.
I am still not sure why this is our issur d’rabonan v. someone else’s aveira. We are talking about challenges, not violation. So, you will have difficulty going to the minyan, so take time off your work and go to the minyan. Of course, this means your loss v/ someone else’s loss, and you are not obligated to do that, although maybe it would be a good humra. I can maybe argue that you are better learned & equipped to absorbe the loss, while a less observant person is not.
Or you can argue that minyan is every day, so your loss is 5x larger, or it is not practical to get accommoded at work every day.
It may be also a difference that during R Moshe’s time there was a feeling that those who are fully observant are an endangered specie, so they have to be protected and nurtured. As R Nosson Sherman’s father was saying to his (elderly) shiur goers during snowstorms – continue coming, who knows if there will be a shiur after you …
