The fNFTs are tradable on an NFT marketplace at a price determined by the seller. However, NFTs are not as liquid as coins and tokens. On a Decentralised Exchange (DEX), it is possible to make an immediate trade with a liquidity pool. On an NFT marketplace, an investor would need to wait for an offer to buy the fNFT. But while they may lack the transactional liquidity of tokens, they allow for the locking and preservation of real world liquidity within tokens that opens up a whole new world of things like stable collateralized lending within the DeFi space that isn't just based on leveraging highly volatile assets.
