transplanting?

i was just wondering why is it people often put there seeds in small containers/pots first and then transplant them once or even twice to larger ones?
is there some kind of upside to doing this?

look up Sea of Green method.

easier to feed and water, no point watering a big pot with a small plant with small roots

Also saves in space and soil/materials, which can be expensive. I would much rather germinate in a cup, so if I loose a seedling in a cup I haven't wasted very much of anything. Then I veg in a one gallon container (or less), and I wont know which plants are the real keepers until I sex and eliminate the males (if starting from seed). No point in allowing potential males to grow in anything like a 3-gal container when they will most likely end up being culled.

Smaller pots = room for more initial starts + less waste + convenience
