imagine a home user with 5mb connection but 100 nodes connected.. thats 0.05mb per node (sending ~1.2mb 100x)
imagine a home user with 5mb connection but 2 nodes.. thats 2.5mb per node(sending 1.2mb 2x)

the second option is better for home user as the block is sent in seconds to just 2 users meaning speedy. also its only 2.4mb total instead of 120mb total.

now imagine it from the receiver side.. imagine a merchant was connected to a home node. the merchant wont want to get data at 0.05mb speed they would prefer 2.5mb speed
so not only will the home user benefit by lowering nodes connected but also the people on the other end would benefit too
its far better that a home user only connects to 1-2 nodes for own benefit and have just enough for own NEED, and let the merchants that have a higher NEED do the higher node connected higher bandwidth/sped connections. as they NEED it more
