More so, there's diminishing returns above a reasonable speed, and below a reasonable amount of lag, and gigabit speeds are well past that point, but for many ISPs the lag is fixed and before that point.
Which is to say, every major telco offers faster speeds than the majority of their subscribers will ever use, often even on their bottom-teir plans, but a significant portion of ISPs have enough lag to affect their users, even on their top-tier plans.
If you're trying to push telcos toward offering a more useful product, don't set a goal for them to offer higher speeds, which are already high enough for the vast majority of customers, but instead push for low latency, which most telcos cannot provide even between the customer's equipment and the telco's equipment.
Fiber providers have excellent latency, and of course that's what you should get if it's an option, but many subscribers are stuck with telcos that use DOCSIS over a cable network or LTE over a cellular network, and nothing can be done to reduce the latency for current generations of those protocols, but there's no technical reason the protocols couldn't have lower latency, so pushing telcos toward offering lower latency could make it happen, creating an actual useful improvement.
