Just because you don't stream video that often does not mean you can get away with slower broadband. It doesn't work like that.
A newly produced streamed video these days will be 1080p or 4K. The recommended bitrates for those resolutions are 8-12Mbps (1080p) to (35-68) Mbps... Those speeds are very much fibre optic speeds.
Of course you could be the 0.0001% of people who strictly stuck to 360p videos and text only websites, but nobody cares about people like that.
* "Fibre optics speeds" is a horrible term btw.
If I do need to stream anything large, I've a £12 contract with 12Gb 4G on my mobile phone, so I just use that as a Wi-Fi hotshot.
