ELI5: Why do wall sockets only have 1 or 2 plugs?

I've always wondered why there were only two. Can't we add more?

There is typically a code (for safety) regarding electrical wiring. There is always the option of running more wires to more outlets, but there is a limit to how many sockets can be wired for a single pair of wires (by code). 

Also a outlet boxes are very standard items - they are low cost because they are made in large volumes and made to common specification. Anything custom will be very expensive. More outlets means more circuits, means more wires, larger distribution boxes and more circuit breakers. 

Lots of things can be done (within the electrical code for homes) but it is a matter of paying a lot more. Most households don't bother with the added expense.
