I agree. There are changes which could be done to squeeze more stuff into the existing blocks, but it's like a max 20% improvement.

Fundamentally, there's no point owning a UTXO smaller than the cost to spend it. Below that, some compromise is always necessary, such as:

1. UTXO shared with a group of friends/community.

2. Trust, but if they screw up/over they can't steal your funds, only burn them.

3. Trust, but if they fail it costs them far more than they gain.

4. Trust, but they can only try to rug *everyone*, not you specifically.

5. Trust, but you and your friends can combine to pay fees to get a UTXO like #1.

You can add reputation and anonymity in there, you can combine these options, you can play with the balance (e.g. size of bond required) but the minimum UTXO size seems to be a fundamental limit. And it's almost certainly one we will reach for many people.

You can add an input and spend it. A (U)TXO has a dual purpose. One is to hold spendable value, the other is an immutable timepstamp in a chain of transactions, forever. The latter also can have value if it is overloaded to be a reference, which is possible in ECC. It may be for the birth of you child, it may be a smart contract, it may be a will that is disclosed after you day. The possibilities for (U)TXO reuse, as of today, are endless, it's more than just the value stored in it. It is essentially infinite memory.
