Is it worth to start a business without a token (because it wouldnt have more use cases than established cryptos offer)?
Let's say you want to start a casino, it would be cheap and easy to create a token to play on it, that way you can provide a huge bankroll for the game at a really low cost. And if you want to use known crypto for your casino then the bankroll will not be cheap at all.
Are there other ways similar of token shilling? Maybe create some NFT sets and offer something for that?
Well, another option is to create a crypto coin but this is the complex way, for it you need to clone crypto and provide a new Genesys Block, after that you need to create some nodes and that will make your blockchain runs. But if your coins aren't on an exchange then it will be impossible for users to buy it and sell it.
