What is the point in Tor if the initial connection data is transferred to Roskomnadzor?

Question

Anonymity

I was interested in how to become an Internet provider, and read that the license and provider of the Internet itself in Russia is Roskomnadzor. (Correct me if I've been misinformed).

And then an idea arose in my head, what is the point of the Tor browser when hiding its location, if the user, upon initial connection, having illuminated the MAC address of his PC on the network, gets into the Roskomnadzor connection registry? After all, then all the information where such a user connected his PC to the network can simply be requested from the regional Internet control authority (Roskomnadzor) ?! Right?!

Scheme in short:

Answer 1

From the point of view of hiding the fact of transferring some illegal information, using Tor is about the same as putting on a Santa Claus mask to deceive video cameras :) Yes, the traffic is encrypted there, but for "these" people (if the task is to hide from them), the very fact is enough turning to Tor or any other means of anonymization - and then "rubber hose cryptography" comes into play, which, as you know, breaks any ciphers.
You are a little misinformed. To obtain a provider license, you must install SORM equipment, which will transmit traffic information to a Big Brother Big Data Center. The RKN is just the sovereign's cudgel, it itself does not decide anything.

Answer 2

Roskomnadzor is not a supplier, but a regulator.
Information about the connection can be obtained from the provider, but it will not have any value, because from it you can only get the fact of connecting to TOR, but not the traffic (or rather, the traffic will be encrypted).
UPD: I didn’t look at the picture and didn’t understand what the poppy address has to do with it.
The provider does not know the MAC address of the end device in your scheme
