You are being completley uncritical. Firstly, you're being dishonest by omission to pretend that Thomas wasn't also taking week+ holidays on luxury yachts (or similar), for which even the most optimistic cost would be tens of thousands of dollars each.
You mean free. If your friend says "hey, my family has access to a beach house next week, do you want to come with?", what does that cost them to invite you? Nothing. Zero. Zilch.
Check this out:
The filing instructions for judicial financial disclosures.
In the gifts section, it says:
" Food, lodging, or entertainment received as personal hospitality need not be reported. Personal hospitality means hospitality extended for a nonbusiness purpose by an individual, not a corporation or organization, at the personal residence of that individual or his or her family or on property or facilities owned by that individual or his or her family. "
The yacht rides, or mansion visits, or private golf course access are all exempt. The only thing in their list that its actually an infraction not to disclose is the travel, as travel is not exempt, even with privately owned means of transportation. There is a line in there that specifically calls out transportation as non-exempt:
" the reporting exemption does not include: • gifts other than food, lodging or entertainment, such as transportation that substitutes for commercial transportation..."
But that line wasn't always there. It was added there for clarification this year, which is part of how this has come to light. Clarence Thomas was disclosing when people paid for commercial travel for him. The things that were excluded were all when people were sharing their private property with him, which according to him, he believed were exempt from the disclosure filings:

"Early in my tenure at the Court, I sought guidance from my colleagues and others in the judiciary, and was advised that this sort of personal hospitality from close personal friends, who did not have business before the Court, was not reportable. I have endeavored to follow that counsel throughout my tenure, and have always sought to comply with the disclosure guidelines. These guidelines are now being changed, as the committee of the Judicial Conference responsible for financial disclosure for the entire federal judiciary just this past month announced new guidance. And, it is, of course, my intent to follow this guidance in the future.”
This episode reflects extremely poorly on Clarence Thomas's honour and judgement, and thus I think given his station resigning absolutely is appropriate.
I'm pretty sure you think his conservative positions reflect poorly on him, and everything else is rationalization.
