Wrong! Lag and data size are important. You are saying that e.g. for a
car only the top speed matters but not the power of the engine. I can be
faster than 200 km/h with a car that has only 1 horse power (by driving
out of a plane...). The other way round also doesn't make sense (a tank
is much slower than a motor bike, although it is much stronger).

A normal user doesn't know that the amound of data is important -
because the game designers have alrady taken care of it.

There are actually many things that have to be taken care of when you
are thinking of adding net support:
- the phyiscal connection limits the amount of data which you
  can transport in a certain time
- the protokoll reduces that rate and can cause other problems. 
  Either it guarantees you that you recieve the data - but that 
  can be whenever (TCP does that). Or it transports the data as 
  fast as possible - but might get lost (UDP)
- The network funktions of the OS might give you additional 
  limitations

And there are definitely many more of those.
