I think this will make more sense once 5G is adopted. But even then carriers will either charge a lot for these data plans and/or severely underdeliver.
LTE is already faster in theory and in practice than most people's home connection. My parents just got a brand new internet connection thanks to the Australian Government, that costs about 2500$ per premises, that maxes out at 25mbps and will never go faster due to being DSL. 4G however can hit 100mbps easily. Mine tests at 130mbps.
The limiting factor for 4G on a laptop is data caps, not speed.
