All I care about is for Bitcoin to succeed in a long term - you put USD requirements over running a node and you are giving the power back, to the very same people that Satoshi was trying to escape from with his great invention.
Do you actually understand that PEOPLE, not only banks will be able to run full nodes in their basements even if block size is 50MB, right ?
You are wrong there. Me and all my friends who are running full nodes are already peaking our upload speeds, with maxconnections=16 and 32 kB upload,
which is speed almost everyone I know here go for. To increase it to 64 kB I'd need to go for 8 MB download package which not only costs too much but
I don't need it for day to day computer use. My upload:download ratio now is 20:1 or more when only Bitcoin client is running on computer. If block size
goes up significantly, there is no way me or my friends will run full nodes. So, you lose few of us here, many others elsewhere, and you'll be left with less
than 1000 full nodes worldwide. Good luck!
Right now I'm running a full node on a VPS because the traffic is a bit rough on the home connection. For people who are invested enough in Bitcoin and want to see it stay decentralized, this might present a reasonable compromise. I keep my wallet in an SPV client and sponsor this node to help keep the network strong.
People already do this for tor nodes and have been doing it for a while. I don't see much reason why people who have benefited financially from the bitcoin network and want to see it continue to succeed would be very averse to taking on this responsibility. It is not something everyone needs to do, should need to do, or even should do. It is one very practical way of adapting to the changing realities of bitcoin though.
