In some sense, this is an argument in favour of bitcoin.
If you see the link from the poster I responded to, you will see that s/he is likely a Bitcoin maximalist, so the only argument they can have is in favour of Bitcoin/"the one true chain".
The link is trying to make the argument that layer-2 projects are not "real cryptocurrency" because the transfer of values are not happening on chain. This is what I was responding to.
I am in favour of innovation in the cryptocurrency space, including the creation of new currencies where necessary, but I think that solving layer-1 scaling by adding the complexity of a layer-2 network should be a last resort.
Of course, companies and individuals who make their money from running layer-2 services will disagree with me, as will holders of currencies whose value depends on the success of layer-2 solutions. For what it's worth, I don't own any amount of any cryptocurrency.
First, scaling layer-1 and implementation of layer-2 solutions is not an either/or proposition. They can be (and are) developed in parallel and one can and should complement the other. Even if ETH2 manages to increase transaction capacity by 5-6 orders (which is quite a tall order) of magnitude there is a strong likelihood that a lot of that will be taken by dapps beyond simple token transfers, and we will be back very quickly in a scenario of network congestion and (relatively) high network fees and consequently demand for payment channel networks.
Bitcoin as well, with all of its forks and different proposals has barely managed to increase its transaction capacity 10-fold with BCH. People will not wait 10-15 years to maybe get something that resembles the capacity from Lightning, so much so that the main story from most bitcoiners is that it should be seen as a store of value (not a currency).
Second,
> companies and individuals who make their money from running layer-2 services will disagree with me
Is a huuuuge ad hominem. I can tell you that there is a good number of developers (myself included, if I may say so) and companies working on this who are more driven by ideals than pure profit. The main reason that I would like to see strong layer-2 systems working (especially in ETH and with stablecoins like DAI) is that so far it is the only feasible way to have a payment network that can actually compete with credit card networks.
To put it bluntly, layer-2 is another case of "Worse is better" if we actually want to have blockchain technology as an alternative to existing financial and monetary systems. Being a purist will not help the people of Venezuela, while layer-2 projects (even custodial alternatives) could.
Long term I agree, that's why I said "a layer-2 network should be a last resort" rather than layer-2 solutions being completely useless.
> Even if ETH2 manages to increase transaction capacity by 5-6 orders (which is quite a tall order) of magnitude
Doing a quick calculation, if ETH2 manages 9,000 transactions per second, that's about 0.1 transactions per person (on Earth) per day. You're right that a reasonable definition of success requires some sort of layer-2 solution eventually, although I don't think we are anywhere near that scale ceiling yet.

Wasn't it you who accused me of being "a Bitcoin maximalist" in an attempt to discredit my position? :-)
Anyway, we'll see how much layer-2 solutions end up helping the people of Venezuela relative to layer-1 solutions:

Decentralized exchanges, games, management of NFT, all that already exist. They are just really impractical/expensive to do on the blockchain, and layer 2 solutions are starting to come already to tackle that. It makes no sense for everyone to wait for every quantum leap in TPS capacity. "Worse is better" have always won.
Unless, of course, your definition of "winning" necessarily goes through the adoption of a blockchain that can not do much else besides transferring its one specific currency. ;)

If people are getting BCH to convert straight to fiat and/or buy food, is it really a fair comparison with an alternative that is creating its own economy?
