If you run a node you will now need 4 times more storage space, can you afford it ?
Among all the stupid reasons to be against bigblocks, this has got to be the stupidest.
Then why are so few people running a full node ?
There are also bandwidth consideration. I have more than 250TB of storage space at home, but limited bandwidth. My Bitcoin Core wallet has crashed for some reason (PC is extremely stable, with ECC memory) and it doesn't manage to recover. It took me weeks to download the blockchain, I'm not ready to do it again.
I wouldn't consider almost 100,000 full nodes 'few people'...
