Frankly, if the company ran even 1% like Uber in the sense of "maybe we'll ask forgiveness" and just do what they like, people will die.
They're usually cooking The food for themselves/direct family, so while accidents/mistakes can happen, they're not motivated by profits to cut corners.
Secondly - the distribution potential for the food is quite small. If something is unsafe to eat, you have a small group of potential sufferers, rather than 100 or 1000 people all over the state/region
Surprisingly, California has one of the most liberal laws w.r.t. cottage food industry of any state: http://forrager.com/law/california

The requirements are not insurmountable.
Please someone do this! There's loads of (mainly) women on Pinterest who explain how they bulk prepare a month worth of food for their families in a day or two, and freeze it/jar/store it. I'd love some near me to prepare more and I could just buy up some of it and throw it in a slow cooker or oven.
That said, I don't think its unnecessary regulation either (unlike some good arguments that could be made for taxis/car-services IMHO).
I would not order from a place where the quality and safety of the food was an open question. I'm more inclined to either order direct from a place, or go to Marly Spoon, Blue Apron or others.
Other is more expensive i.e. cross-country 1-day shipping of frozen, dry-ice packed, or non-perishibles. There's definitely a market for this i.e. https://www.goldbely.com/ but definitely a narrower market (i.e. $80 for 2 Joe's pizza pies from NYC).
One of them called Chefy was doing this same exact concept. I think I have their contact details at home if you are interested in this space.
I live in an area with so many Chinese people, but can't find a decent dumpling restaurant. And frozen dumplings from Safeway don't cut it. I'm sure your average Chinese household within .5 mile radius from me makes 100x better dumplings than I could buy commercially anywhere near me. Would love to just buy a few dozen frozen dumplings from the best Chinese mom near me and give her a marketplace to do it.
Alternatively, become an activist and change agent in the political sphere, and try to get some of these barriers torn down.
