But if he touch obito defence gudoudama he turns to dust in a instant
How long can Obito survive w/o breathing? Hercules at max can instantly suck in 370 trillion tons of air (that's enough to fill the entire Atlantic ocean)
an attack called minority would would fodderize obito cause it literally reverse everything. For example if you could fly it'll make you unable to fly, reverse the flow of your blood, if you're moving at high speed it could put you at a stand still, if you're completely healthy then it'll deteriorate your health and eventually kill you etc. They only way to Survive minority would is to try kill yourself so that the reverse effect starts to bring you back to life but Obito wouldn't figure this out as it happens to fast.
And that's just using minority would on your opponent, the user can use it to control gravity around his body, allowing himself to fly, regenerate limbs, increase the speed of his attacks to crazy speeds. The power of minority would is basically infinite. Obito would be turned from having lots of charka into a simple fodder with zero chakra by the effects of minority world
