my whole point is that just because ETH ASICs aren't popular it doesn't mean they don't exist or are impossible to create.
as for ASIC-resistance, there is no such thing! so far every mining algorithm that i have seen have been firstly making it different from SHA256 (for example in case of ethereum it uses SHA3) so that bitcoin ASICs can't be used, and sometimes making it "difficult" to create an ASIC (like ProgPoW algorithm) while that difficulty is only in theory and untested.
besides i've always found this argument absurd that ASICs centralized mining while GPUs don't. because having a lot of money to buy equipment and build a big mining farm to own a large hashrate and having access to cheap electricity centralizes mining, ASICs are just icing on that cake. the same millions could easily go into building GPU rigs and increase the difficulty so that individuals with moderate electricity cost can no longer mine that coin.
