If people are left bereft by the closure of churches, withdrawal of sacraments, withdrawal of fellowship etc. etc. - they will feel themselves to have been spiritually betrayed; and will never again trust their Church.
But if people adjust-to the coercively-imposed unilateral-withdrawal of their Church; and manage their spiritual lives satisfactorily, well, or better than when they attended Church - these people will realise that they do not need the Church.
It is Catch 22.
Either way - Churches are finished. By which I mean that, even if they survive in some form as institutional structures; for serious Christians, Church will never again be the origin and focus of their Christian life.
