You are right. It is the business or execution side of the business that matters. I got another domain very close to what I wanted with 3 extra letter(suffix)

You are right. It is the business or execution side of the business that matters. I got another domain very close to what I wanted with 3 extra letter(suffix) for few hundred dollars from a squatter. 54k for the domain is still higher(unless you have some angel money to throw at it). I'd use that money to bootstrap my project.
