> You can definitely replace petroleum for many of the things you listed - or find alternative technologies that don’t require it. You can live without plastic bags or plastic clothes for instance.

Not really, not at this scale, or this price and convenience.

Most things you enjoy today are affordable because we have fossil fuels. The entire supply chain of every single product you can imagine is very dependent on fossil fuels. We're not even capable of making proper roads or tires without petroleum derivates, without these two alone nothing gets to you. Investigate a bit, you'll find petroleum and petroleum derivates a prerequisite of virtually everything.

Renewable energies look like a solved problem today with wind and solar, but it seems like everybody forgets that the entire supply chain to make them is 100% petrol dependant from mining raw materials to the final delivery. In a world without petrol these would be orders of magnitude more expensive, if even possible at all.

Not at this scale and price and convenience.

We can absolutely do so for higher prices. And with solar panels becoming more efficient, cheaper, and more ubiquitous with each passing year, we may find that a lot of those "higher prices" were really just "higher energy input costs", and we will be able to come very close to what we have now. (I don't know for sure—this isn't an area I keep abreast of.)
