Even the once ubiquitous Linksys BEFSR41 from 1999 had an integrated switch and Ethernet switches were a thing in business environments well before that .
My take on experiencing a given time period is to try to take advantage of the best that was available then, except when going for the nostalgia element .
My experience with broadband Internet at home started in early 1997 with peak downstream speeds of over 5Mbps during off-peak hours . I also bought my first 5-port switch in 1999ish, AFAICR (Netgear FS105). I am pretty sure that qualifies me as an early adopter, at least where I live .
That being said, I completely understand why someone might want to use a hub or even 10Base2 over coax,or even so far as simulating dial-up Internet, but that is taking it a step too far for me personally and, I would guess, a fair number of other people.
Anyway, we all have our specific retro kinks, some of which are only shared by a select few and that's fine by me .
Good luck, OP, and have fun!
