I get that, but you still can't get anywhere near 100% renewables even going forward from right now. You need a huge investment in new power plants to get off of coal, and right now that would involve quite a bit of nuclear because renewable sources are not yet at the point where you can rely on them to power the grid all of the time regardless how many you build. Electric aircraft aren't viable and it'll be a very long time until they are, if ever, for the longer routes. And then there's the everyday items, from antifreeze and tennis rackets to toothbrushes and crayons to detergents, deodorant, rubber alcohol, thousands of ubiquitous products that you use in everyday life without thinking they come from oil at some point in the chain.

There are algae-based and other replacements being worked on for a lot of them, but we aren't remotely close to being able to get rid of them completely. That's why I say it's a matter of how fast you move, not whether you get there.
