Sorry for the uppercase, but transparent proxies are dangerous, *especially* if users are not aware of them.
Applications that are not explicitly designed to use Tor can often leak data or be vulnerable to malicious exit nodes.
Also, this pattern can create false sense of security.

It'd be nice if you could simply point tails at this but afaik it's bad to do tor over tor.
I use this for malware reverse engineering for example.
The proposed setup also makes devices properly configured to leverage tor "anonymity" features vulnerable to misconfigurations of other devices using the network that is routed over tor (through the same circuit) in various ways.
Tor provides obscurity, not security, even for applications designed to use tor. And even then obscurity isn't lower, in clearnet you have zero obscurity.
