> as a regular person requesting IPv6 space you'd just ask your ISP

In real life these requests don't lead to IPv6 allocation, no matter how they're asked or how often. Here are a few of the responses I've received just this year.

    "At this time we are not able to provide a IPv6 unfortunately."
    "We regret to inform you that, at this time, we do not offer IPv6 support."
    "I wanted to inform you that IPv6 is currently not available"

Past that: Over 15yrs of asking various ISPs (large and small) to make allocations available, none of us ever budged the IPv6 needle.
