Unprovable? Read the administrators reports about the financial difficulties! They are available. How do you think they were written? Do you know what an administrator does (obviously you will now as you'll go away and google)
Basically, you claim to think it's dodgy that the business was incorporated 4 years before the administrators were called in, and 5 years before the company was dissolved. Financial problems started due to covid a year after incorporation. Covid could not be predicted. Therefore the company was set up with no expectation of financial problems.
I'm not going round in circles any longer, you've clearly picked your narrative and have no interest in facts.
Btw running businesses as limited companies is normal. It's how the vast majority of businesses in the UK that are bigger than one man band type operations are run. They are not some kind of devious liability avoiding device used by fat cats.
