2.5 is still really new in the networking space and nobody has hit economies of scale yet. I very much also want to build out my home LAN to be entirely 2.5g compatible since 1g is limiting for my NAS use case (video storage), 10g is overkill and not supported by my client devices, and I only need 16/24 ports. but good God the hardware just isn’t reasonable yet.
You pretty much have to bite the bullet if you really want 2.5 right now. What might honestly be worthwhile is finding a used enterprise 1g switch with the number of ports you need, and will still be “enough”, as those can be had for only a couple hundred dollars. Sit on that for 2-3 years until the 2.5g and 5g hardware market starts to fill out and you can decide how badly you need 2.5g then
But of course, such based individuals will never be billionaires. Specifically because their basedness precludes them from being psychopathic enough to commit the kind of cutthroat, violent exploitation of tens of thousands of workers’ labor inherently necessary to amass such wealth.
