The whole point is having the
option, yes. But it makes no sense in having
only USB-C ports and nothing else. Apple seems to agree, they added a couple ports back in the M2 Macbooks.
Quality Thunderbolt 4 hubs cost about $150-500, which is fine if I need to extend the selection of ports at my desk, but there's no point in having everything on one USB-C port just because it's technically possible.
