Sure, but according to the article, he received the 100k bill because of peak traffic of 60TB of bandwidth per day over several days. If you have a dedicated server in a colo, then a 10GbE connection is very common these days. With a 10GbE connection, you can serve 100TB of traffic in a single day. Hence, if the colo had the same prices as Netlify for traffic, then a single server with a 10GbE connection would be sufficient for such a high bill, no serverless and infinity scaling required, just absurdly high traffic costs.
