There is no need to ban basant, but there is some serious need to ban razor sharp dor, and possibly a restriction on flying kites on the roof tops. Kite flying in open fields should be encouraged, and underage children flying kites on unsafe rooftops should be classified as child abuse.
I generally have very fond memories of basant and kite flying.
Basant means end of winter, and also it marks change of leaves by trees. So it is celebrated, Baisakhi is the beginning of hindu month of Vaishakha, second month of Hindu calender, first of Bengali calender.
