Propagation with roots after a plant has been in the water is one of the easiest ways, and like you said, anyone can do it. I did not yet tried with tomatoes but did with some other plants. I have to be honest and say that luckily, we do not have to try that much in my country since you can get a plant from anyone who has it but I think it is similar all over the world. People who grow their own food are always happy to share their plants so most often if one person has something, it will give his neighbors a sampling to grow it for themselves. Thank you for sharing this 💚
