Depends a lot on what the monopoly in question is.
1. How much room for innovation is there?
2. How hard is it to substitute the good / service provided by the monopoly?
In the case of food delivery apps there isn't much room for service improvement. A monopoly here probably isn't preventing much innovation. How much better can you get at delivering food from a restaurant?
And there is an easy substitute in terms of driving to the restaurant yourself, so if the monopoly tries to jack up prices too much they will steadily lose customers. The prices now are so high that they have already lost me. I use those apps < 5 times a year.
