Technically, scp does create directories if you specify the -r option but that means you need to copy the entire directory and not just a single file:

-r Recursively copy entire directories. Note that scp follows symbolic links encountered in the tree traversal.

Example using scp locally:

/home/blytsplyk: ls -lr dir1
total 4
drwxr-xr-x 2 blytsplyk users 4096 May 16 19:30 tmp
-rw-r--r-- 1 blytsplyk users 0 May 16 19:27 file1
/home/blytsplyk: ls -lr dir2
ls: cannot access dir2: No such file or directory
/home/blytsplyk: scp -r dir1/* dir2
dir2: No such file or directory
/home/blytsplyk: mkdir dir2
/home/blytsplyk: scp -r dir1/* dir2
/home/blytsplyk: ls -lr dir2
total 4
drwxr-xr-x 2 blytsplyk users 4096 May 16 19:31 tmp
-rw-r--r-- 1 blytsplyk users 0 May 16 19:31 file1

As for the original question, while your home directory may not have the same name on the remote system as it does on the local system, by default, if you do not specify a directory name, scp will use the home directory on the remote system when copying the file. Therefore, if you simply want to copy a file from your home directory on one system to your home directory on another system, you can just do this:

scp file user@server:

There is no need to specify the trailing ~/. In fact, if your account name is the same, there is no need to specify user@ either. And, finally, if you set up your ssh keys, there would be no need to enter your password. I don't personally use sftp since I don't have a need to automate transfers between Windows and Unix machines but I believe newer version of sftp take advantage of ssh so you would still need to set up ssh keys if you want to avoid manual password entry.

NAME

       dircmp - directory comparison

SYNOPSIS

       dircmp [-ds] [-w n] dir1 dir2

DESCRIPTION

       The  dircmp  command  examines dir1 and dir2 and generates various tabulated information about the contents of the directories. Listings of
       files that are unique to each directory are generated for all the options. If no option is entered, a list is output indicating whether the
       file names common to both directories have the same contents.

OPTIONS

       The following options are supported:

       -d	Compares  the  contents  of files with the same name in both directories and output a list telling what must be changed in the two
		files to bring them into agreement. The list format is described in diff(1).

       -s	Suppresses messages about identical files.

       -w n	Changes the width of the output line to n characters. The default width is  72.

OPERANDS

       The following operands are supported:

       dir1	A path name of a directory to be compared.
       dir2

USAGE

       See largefile(5) for the description of the behavior of dircmp when encountering files greater than or equal to 2 Gbyte ( 2**31bytes).

ENVIRONMENT VARIABLES

       See environ(5) for descriptions of the following environment variables that affect the execution of dircmp: LC_COLLATE,	LC_CTYPE,  LC_MES-
       SAGES, and NLSPATH.

EXIT STATUS

       The following exit values are returned:

       0	Successful completion.

       >0	An error occurred. (Differences in directory contents are not considered errors.)

ATTRIBUTES

       See attributes(5) for descriptions of the following attributes:
