I think it is also helpful for people who are sick, bedridden, or elderly and cannot move, as well as for those who are in prison or in other difficult situations. For them, it is a great consolation to be able to see and participate in the Holy Mass through these means.
I believe it is especially valuable for someone who must stay at home to take care of sick children or others. They can still assist spiritually and be helped in their prayer through this.
