You're confounding using Javascript for web development and "loading megabytes of tracking code". They are not mutual exclusive, nor have anything to do with the development side of it. Advertising and tracking are a business decision, not technical one. Well, you're entitled to not visit/use those websites if the megabytes of JS don't serve you. That would be the cost of the decision made to use Javascript by those websites, to have people that share your opinion not using them. And cost is a subjective factor dependent on multiple things and hidden from the user, so when you judge a website to be using Javascript without need, you're basically saying that you know better the cost to the developer than the developer itself.
