More blocksize essentially means more opportunity to capture transaction fees. This necessarily leads to an incentive to create bigger and bigger blocks therefore considerably increasing the cost of running a full node.
Yes but...
1. non mining nodes are already doing this altruistically.
2. Technology is getting better and cheaper all the time.
3. As adoption widens, there may be more nodes coming on board, even if that hasn't happened in the last 2 years
4. The more you move things offchain, the more you introduce centralized elements.
So, you may have some arguments against bigger blocks, but I'm not like, you know, super convinced.
