Except almost none of them did. You’re suggesting going back to having next to zero food delivery options in a world that continues to see COVID spikes and could have future localized lockdowns. I also think this overlooks how much of a QoL increase these services are for people with limited transportation options or mobility problems or other health issues making it hard for them to get out of the house. These services are more than just conveniences to them. They are massive upgrades to their lives.
Maybe it’s different where you live, but over here many restaurants did have their own delivery service before Just Eat etc. entered the market. In the beginning, they made things cheaper and easier for the restaurants. But recently, I read a lot about how they increased the fees for the restaurants, who would encourage customers to go back to using their own website instead. Enshittification as always.
