On the other hand, does an approach like this help?

\version "2.20.0"

basicdistance = #(define-scheme-function (n) (integer?)
  #{ \paper { system-system-spacing.basic-distance = #n } #})

linewidth = #(define-scheme-function (n) (integer?)
  #{ \paper { line-width = #(ly:cm n) } #})

\paper {
  indent = 0
}

\linewidth 10
\basicdistance 30
\new Staff {
  \relative c' {
    c1 \break
    c1
  }
}
