Not really.

If you were able to buy 100% of Porsche, you would be able to sell it again for a similar amount because the business would continue to operate and make money. The value is in the constant stream of customers that give Porsche money in exchange for cars.

If you bought 100% of Bitcoin, you would not be able to sell it for much because the value is in the widespread ownership of Bitcoin and its use/potential use as currency. Just like the 'market cap' (money supply) of USD is a few trillion but only so long as a few hundred million people hold USD.
