Yes, that's obviously true. But for my part, whatever overhead these tools do add is low enough that, even for no-crap sites like HN, if I can notice it at all it's within the page-load-latency noise threshold. Moveover, the increased browser stability, laptop battery life, etc. is an overwhelming win.
FWIW, I just fired up Chrome on HN and messed around with the dev tools a bit to see if there was any obvious overhead. Without taking the time for anything like rigorous analysis, loading HN with all extensions disabled vs. uBlock Origin and Privacy Badger had no immediately obvious effect on page load+render times. The superficial results agreed with my intuition: I'd have to collect data and run an analysis to uncover any added page load latency.
