No it's not. By abolishing the mutual defense pact of all those different nations it will simply Empower a different group of people. Who are just as bad actors as NATO has traditionally been. And any claim to the contrary is pants on head crazy.
Are you seriously insisting that Russia who is currently invading ukraine. And China who is poisoning the reefs and fishing spots around their neighbors in order to hurt them while also saber rattling at Taiwan would see the dissolution of NATO and say okay we'll be good people now? Is that seriously what you're implying? I'm not saying they're worse than NATO had traditionally been. They're pretty on par. But let's not act delusionally here.
