Why was job specialization and domestication better than hunting and gathering?

If I list to you the benefits of ”job specialization” and ”domestication” you'll get it why.

Benefits of ”job specialization”:
1- It boosts your productivity
2- It helps you find a proper job
3- It helps employees become independent
4- It’ll get you more desirable by people (they'll want you more and more)
5- It'll make you more educated
6- It'll give you bigger chance to socialize
7- Saves you lots of time
8- It’ll give you a higher pay rate
9- It'll raise your job-accuracy

Benefits of ”Domestication”:

Domesticates have provided humans with resources that they could more predictably and securely control, move, and redistribute, which has been the advantage that had fueled a population explosion of the agro-pastoralists and their spread to all corners of the planet.

When both advantages above are compared to hunting & gathering (despite they were the ultimate survival source), you'll form quite some disadvantages of hunting & gathering:

1- Not being able to find food when on the hunt. So when hunter-gatherers do not find food they have to stretch their food to survive on what they have provided.
2- The inconstancy of food and supplies
3- Being killed by an animal while hunting
