This story just made me so sad! It makes sense to some extent for tag to be banned from the playgrounds, however, no touching at all is getting a little extreme I think. It is important for human beings to have physical contact. For many I think it helps to boost self-confidence and self-esteem. Even if it may not be seen as necessarily crucial to the child, taking it away and prohibiting a student to do something so natural, is something which saddens my heart.
I know this is not the final decision made on what to do, but I did want to make a comment on the original plan nonetheless. It may not appear crucial to learning or curriculum or education at all, but it does affect the learner and without a learner there would be none of the above, therefore what happens on the playground and outside of the classroom is also important.
