The goal is to eliminate CO2 emissions, not eliminate the use of oil generally.
For plastics production, that goal could be achieved by migrating extraction, refining, manufacturing, and transport to carbon neutral energy sources.
Of course, moving away from non-biodegradable plastics, in general, is also a good idea for a host of other reasons.
But given oil is also used in, for example, the production of fertilizer, we're probably gonna need to be able to extract it and use it sustainably for a while yet.
