This is a sea change akin to the discovery of double-entry bookkeeping or the common stock corporation. You may reside in one jurisdiction your entire life, but the whole point of the internet is to connect humanity. You have no doubt interacted with hundreds or thousands of people in your lifetime online that reside in other states or countries than yourself.

If you want to coordinate with people across jurisdictions to create a venture or a charity or a political movement or a software start up or a video game project or create an artistic franchise, traditionally you need a pre-established relationship to do so. Because one person ultimately has to be in charge of finances if capital is involved. This creates a touchy situation. What happens if your partner in China or Argentina or Zimbabwe wants to custody the funds? You need to not only trust the person to be the treasurer and not run off with the money, but also the local banking laws and rules guarding those bank accounts. This makes coordination across distances difficult and unpredictable and fraught with risk.

Contrast that with placing those funds in a multisig, where you and your 3 teammates (from 3 different countries) all must sign-off on every expenditure from that multisig smart contract. Maybe you're ok with 3 out of 4 signing off on expenditures, that's fully customizable, since it's all code. You can also effortlessly swap between different currency pairs, whether that be Ether, or Bitcoin, or USDC, or Japanese Yen, and reinvest the treasury into yield generating strategies (since there is demand for on-chain loans and there does exist permissionless 24/7 on-chain money markets).

Now, don't lose sight of the big picture, because there's 7-8 billion human beings on this planet, and currently it is nearly impossible to coordinate, raise, and manage capital in a meaningful way for the vast majority of these humans. This is unlocking the capital availability of Silicon Valley for the whole world.
