there is much point in doing 可以说成there is much use in doing吗

there is much point in doing 可以说成there is much use in doing吗 关于there is not much point in doing sth. there is no point in doing sth .如果在point前加上much就要把 no变成not,为 there is no point doing还是in doing? there is no use/point/sense in doing sth.请问其中的in分别能不能省略? 句型there is no point in doing sth. there is no point in doing中的point可以改变吗? There is no point doing there is no point in doing sth.的in可以省略吗? there is not much use There is no point doing 啥意思? there is no sense in doing sth
