Loosely translated, "I am above the law."
Pretty much.
Back to the Canadian Ture analogy, he's right, it is a stupid example because he hasn't fleshed it out to encompass the full reality. Fully fleshed out it goes like this - If the people that went into Canadian Tire to steal something were the same people that paid to build the company, but who then profited when it was later sold for double what it cost to build, then no, there is no way for them to later justify going back in to "take a few things". It would just be theft pure and simple.
The taxpayer paid to build the 407 out of the tax coffers, the government then sold the rights to operate the highway for twice what it cost to build, and those proceeds went back into the tax coffers. The taxpayers as a body were well-compensated by that sale. Those taxpayers who actually use the highway pay for the convenience under a user-pay system.
If the government had NOT sold the operating rights to the 407 to 407ETR and kept it in-house, the same people who steal from the 407 now would still be stealing from a 407 under government operation. Only the excuses used to rationalize the theft would change.
