Let us assume the usage of Bitcoin grows so that the network has to process 40,000 transactions per second.
Assuming 250 Bytes on average per transaction this would result in a data stream of 10 Megabyte per second or 80 Mbit/s just to be able to receive all the transactions.
This does not include the traffic overhead of forwarding the transaction information to other peers.
While 10 MB/s does not seem extreme in the context of high-speed fibre and 5G mobile speeds, it would effectively exclude anyone who cannot meet this requirement from running a node, especially in countries where high-performance internet is not affordable or widely available.
Users also have many other demands on their bandwidth and cannot be expected to expend this much only to receive transactions.
Furthermore storing this information locally would result in 864,000 Megabytes per day. This is roughly one Terabyte of data or the size of a hard drive.
