The thing is, the reason food delivery workers get paid so poorly is because there is a large number of people willing and wanting to do the job.
If people were not able to make ends meet doing that job, they would stop doing it and do something else and that would create a lack of supply of delivery drivers.
This would drive up the pay rates of delivery drivers because companies would not be able to get workers.
What exactly does setting a high minimum wage for a job do?
Well for starters, lots more people want to do the job, so you have even more excess supply.
But the biggest impact is on other jobs.
Why would someone go to college or university when they can earn great money doing deliveries.
High minimum wages have a knock on effect of decreasing the supply of skilled workers in other fields driving up the wages of people in those fields.
The best thing for higher wages is to just have no minimum wage, this forces people to upskill into fields that have higher wages which has the net effect of reducing the pool of people willing to do the lower paid jobs (driving up the wages of lower paid jobs).
You mess around with supply and demand at your peril, it just requires more messing around to fix the issues it causes and then more messing around to fix the issues those issues.
