The question is absolutely not "can more than 2mb can be uploaded?" The question is not, is it possible to run a node? The question is, at what point do bandwidth limitations disincentivize the operation of full nodes to the extent that centralization endangers security and fungibility? We already know that over the past several years, as block size has gradually increased, operating nodes have persistently fallen. Would you suggest that block size, which is directly related to bandwidth requirements for nodes, is not related to the perpetual decline in nodes? As a node operator, I can tell you that bandwidth is the only possible reason why I wouldn't run a node (as opposed to storage, hard disk resources, hardware). That's the only pressure. Most people do not have unlimited fiber connections. Most people have capped-bandwidth cable or low quality DSL. So the question is not, "can these people run a node, using much or all of their upload bandwidth? Or will they choose not to? The latter is what we must contend with -- and is related to the perpetual decline in nodes over the past couple years.
