Rails is an opinionated framework. Many very smart people already came up the best practices for building a web application through several dozens of releases over almost 10 years. Just follow the best practice. If you are not happy with Rails being what it is, just change it to some other framework. Having 50-100k loc files sound horrible by the way. I would not want that to happen in Rails.
