the GDAX team will wait for additional regulatory clarity before we decide which ERC20 assets to support on GDAX. ... Coinbase will only list assets after they are listed on GDAX
You're thinking too small. Think smaller and larger cap stocks deciding to go public through a token instead of through an IPO (where they generally lose 5 to 10% of their capital raised to an underwriter, and as was seen with the Dropbox IPO, was priced way too low)
This probably makes sense. I've wondered looking at coinmarketcap.com which tokens every could possibly be adding. The top by market cap are: EOS (a placeholder until they're mainnet goes live), TRX, and USDT. None of which seem like good candidates for coinbase or even gdax listing
Very few of the current altcoins excite me. But I like Bitcoin and Ethereum (Ethereum partially for the reason mentioned above). The tokenisation of assets could be an interesting development.
Even with the institutional funding they seem to be getting? If you're right, I'd be surprised because it's reasonable to assume funding and collaboration would include some demand of that nature.
Basically no.
