You can make do without oil. Water, not so much.
1%er countries can make without oil for transportation in the somewhat near future. The less endowed or those subject to political corruption and thus collective theft(like Nigeria) can not afford more expensive renewables and their infrastructure isn’t even ready yet.
Oil is a key component of most food production and shipment for the collective.
Plus, those in third world countries live on crappy grids and often use generator power fueled by gas or diesel.
Pharma makes drug, of which someis for mental health.
In places like the Southwest, properties far in the desert can have water shipped to the location for a fee, and that probably comes in a diesel truck, although maybe in the future, such transportation will be electric.
Oil pumps up the property values of rural land because it facilitates commuting, this allowing cities to pursue revenue and shove people out by gentrification. In the future, the EV may suffice for cheap affordable transport for the low income masses, but oil is what allows this to happen here and now.
