I disagree, this logic doesn't work always unless you have investor money lying around. For a bootstrapped business, it could mean living or dying. As an example, a client of mine was paying close to $5000 per month in server costs simply because of the scale of traffic they had on their site.
By re-writing Wordpress in Elixir, I was able to bring their costs down to $1000 odd per month. It's actually cheaper than what any of their competitors are paying for, in servers as well.
This $4000 in savings actually allowed them to hire an additional full time developer to maintain their site.
So, your logic only works for certain use cases, not all.
