> Personally I don't see holders as freeriding.

The network has ongoing costs and only people that spend money contribute to, unless there's a tail emission. In that case, in addition, everyone holding contributes to maintenance of the network to the degree they benefit from it's maintenance in the form of debasement of their savings, which go directly to the miners keeping the network alive. Holders are free riders in bitcoin, game theory wise this is a fact.

> No blockchain will be able to both accommodate retail transactions of 50,000 tx/s like VISA and also be decentralised

This is a statement of fact but has not been thoroughly demonstrated. The 2 bottlenecks to throughput are 1) block size, and 2) network latency between nodes. Block size is only an issue for decentralization if you have to store all historical data forever to get theaximum security guarantee possible. Mimblewimble eliminates this requirement, and therefore enables the same decentralization regardless of block size. At that point, block size is only limited by how fast transactions propagate across the network, that is, latency, and verification of them, which is trivial, within the block time. You can have 1GB blocks in mimblewimble and have the block chain shrink one block to the next with no sacrifice in security guarantees.

All transactions count.

> Yes, monetary exchange is public to everyone. But the source/destination of the exchange are as anonymous as we need them to be.

You don't really believe that do you? This is a system built on cryptography and we just accept that our finances are open to anyone, to be blacklisted, to make a single mistake and our entire transaction history can be tied to us, and even, other peoples history can be erroneously tied to us, weust behave with the most rigorous sterile technique or anyone anywhere can know everything we have and everything we have ever bought. You believe this is all we need?

You can voluntarily remove anonymity for example in Monero with viewkeys, and selectively remove it with transaction keys for individual transactions. You can confirm issuance is not being violated with range proofs. Greg Maxwell's bulletproofs are formally proven, and implementation has been thoroughly audited.

Fees are an issue. If I have a not insignificant sum in bitcoin and I can't move it, bitcoin is broken. I've saved nothing, I've thrown it down a well. I don't like to talk about this because my above points are the cause of it and the solutions I talk about that exist already resolve it, so it's not something that we need to go into depth on. But, I did an analysis about this a while ago that I published on nostr and I think that bitcoin fees will rise asymptotically to reach the median transaction value, which is a positive feedback loop. It's not a problem until it is, and it is already a problem for a lot of people.

You can stop fractional reserve banking. It began because moving and protecting gold was expensive. Moving and protecting cryptocurrency is cheap, people don't need custodians, but we are getting fractional reserve bitcoin because it is artificially kept expensive. The tools exist to alleviate this, you can, right now, have astronomically higher amounts of commerce on a layer 1 chain directly than bitcoin provides, and I'm not talking about some sham scamcoin like iota or whatever. The solution was developed at blockstream! It was initially a BIP!
