Who gets to mount a filesystem isn't necessarily the same as who gets to access it. Imagine a filesystem in /etc/fstab with 'user' in its properties, which allows a non-root user to go mount /path/to/filesystem ... but once they do so, whether they can access it or not depends on its file permissions, not who mounted it.

Root doesn't get access to a filesystem because it mounted it... it gets access because it's root, and has access to everything local no matter what. (Using root all the time is an extremely bad idea, by the way.)

NFS mounts are profoundly not your machine. You don't have their root, you have a root, which they aren't necessarily forced to trust. Once you mount it, who actually gets to access the files depends on what the file permissions are and what the NFS server is configured to do.

It's telling you "permission denied" because the NFS server is denying you permission... It's not really keeping secrets from you. Try accessing it from the owners of those files.

quotaoff

QUOTAON(8)						    BSD System Manager's Manual 						QUOTAON(8)

NAME

     quotaon, quotaoff -- turn filesystem quotas on and off

SYNOPSIS

     quotaon [-g] [-u] [-v] filesystem ...
     quotaon [-g] [-u] [-v] -a
     quotaoff [-g] [-u] [-v] filesystem ...
     quotaoff [-g] [-u] [-v] -a

DESCRIPTION

     Quotaon announces to the system that disk quotas should be enabled on one or more filesystems.  Quotaoff announces to the system that the
     specified filesystems should have disk quotas turned off.	The filesystem must be mounted and it must have the appropriate mount option file
     located at its root, the .quota.ops.user file for user quota configuration, and the .quota.ops.group file for group quota configuration.
     Quotaon also expects each filesystem to have the appropriate quota data files located at its root, the .quota.user file for user data, and
     the .quota.group file for group data.  These filenames and their root location cannot be overridden.  By default, quotaon will attempt to
     enable both user and group quotas.  By default, quotaoff will disable both user and group quotas.

     Available options:

     -a      If the -a flag is supplied in place of any filesystem names, quotaon/quotaoff will enable/disable any filesystems with an existing
	     mount option file at its root.  The mount option file specifies the types of quotas that are to be configured.

     -g      Only group quotas will be enabled/disabled.  The mount option file, .quota.ops.group, must exist at the root of the filesystem.

     -u      Only user quotas will be enabled/disabled.  The mount option file, .quota.ops.user, must exist at the root of the filesystem.

     -v      Causes quotaon and quotaoff to print a message for each filesystem where quotas are turned on or off.

     Specifying both -g and -u is equivalent to the default.

     Quotas for both users and groups will automatically be turned on at filesystem mount if the appropriate mount option file and binary data
     file is in place at its root.

FILES

     Each of the following quota files is located at the root of the mounted filesystem.  The mount option files are empty files whose existence
     indicates that quotas are to be enabled for that filesystem.

     .quota.user       data file containing user quotas
     .quota.group      data file containing group quotas
     .quota.ops.user   mount option file used to enable user quotas
     .quota.ops.group  mount option file used to enable group quotas

SEE ALSO

     quota(1), quotactl(2), edquota(8), quotacheck(8), repquota(8)

HISTORY

     The quotaon command appeared in 4.2BSD.
