Lets imagine that I have a profit running full node, OK?

My next thing will be: setup 100 nodes and increase my profits 100 times
What next? setup 1000 nodes... Etc... Etc

This is economically impossible

Well, if you're setting up 1000 full nodes then you're doing a lot to help the network, so I'd say you'd deserve a good chunk of donations (we're not trying to force anyone to donate, just allow anyone to prove that a full node is associated with a specific address). Remember that 1000 full nodes requires (currently) 20 TB of hard drive space, plus probably several terabit per second of bandwidth, maybe even a petabit, plus 1000 rounds of checking each new block and each transaction.

If the system that proves you're running a full node allows you to claim the same node several times, it's not a good proof system. That's exactly what someone trying to make such a system would have to solve (and why such a system hasn't been made yet).
