I'm with you up to a certain point. A stock is a piece of ownership in the company and if you get in early during an IPO, it can be super lucrative. Even then owning small amounts of stock is no different than owning an altcoin. People just want the stock to appreciate and if it has a dividend that's no different than staking.
In the end all you can point to is that you still technically have ownership in the business while with an altcoin all you own is....=(
