In short, it is our effort that brings food in our table. Bitcoin is just one of the currencies we received from that services so I think it isn't correct to think that it is the Bitcoin that gives our food to our table.
In real life also we have to earn food for ourselves like by working and earn money similarly for Bitcoin also you have to do some work or put efforts to acquire it any way you find possible whether it's investment or you want to earn it.It is a currency as well as investment asset which can bring you anything you want we can measure in terms of money.
Exactly as you said, in this world nothing is instant, anything takes effort to get it. Bitcoin can make a life that is lazy to cook can enjoy fast food by ordering it online. They can sell Bitcoin or pay with Bitcoin if the place that provides the food accepts transactions in Bitcoin.
Bitcoin will never just come without any effort to get it unless the person is lucky to get Bitcoin due to a transaction error made by someone else. Bitcoin is only an intermediary, you have to try to get the intermediary so that the food can come to the dinner table.
