To get sensible modern speeds (I’d categorise as around 1-200Mb) you need modern fibre infrastructure. By the time you’ve invested in that then the hardware can easily deliver 1Gb or even 10 with newer XGS-PON.

So I’d say yes I don’t need a gig, but also internet delivered over old copper phone infrastructure doesn’t really cut it anymore either. It’s nice to have options available to easily upgrade if/when it is needed.
