How to create a global module from a package with go.mod?

Question

go

It is assumed that I create a folder in C:\Users\...\go\src\github.com\myname\slices, for example, for convenient work with slices. I am writing a package package slices, and now I want to use it globally in any code of my repository github.com\myname\...
. I know that you need to initialize it first and then register it in the folder with the code that imports it

go mod init
go mod edit -replace github.com\myname\slices=C:\Users\...\go\src\github.com\myname\slices
go mod tidy

But, why can't I just access my local code repository via github.com\myname\slicesglobally and without pandemonium?
