The odds of having a cable under 100m to a DSLAM basically rounds to 0.

At an highly optimistic 1 mile you’re already down to 20Mbps and most people are significantly further than that. Remember it’s the physical distance of the cable between the actual devices that matters and that’s not straight.

depends on location. and on greed of the telco. i used to live within 100m of dslam. in cities with dense construction/etc it's achievable. also, with g.fast it's 1000 aggregated at 100m. for longer distances numbers are 200 m 600mbit, 300m-300mbit, 500m - 100mbit. numbers are not too bad even for suburb. For comparison, high speed mm wave 5g needs to be deployed any 100-200m in order to get proper speed/penetration.

admittedly, even g.gast it's not as good/scalable as DOCSIS or Fiber, but it could be used and deployed "back in a day" as perfectly good solution. and even today it's not that bad for majority of population, if properly deployed

as anecdote , i saw like 20 years ago privately deployed/managed DSL systems in kibbuz. wonder what they have now

Again you can’t directly compare distances between 5G and DSL because the wire isn’t taking the shortest path through 3D space between teleco equipment and your modem.

Also a single 600-700MHz 5G tower can cover hundreds of square miles with 5G service with up to 250 megabits per second. 2.5-3.5GHz can still hit several miles with up to 900 megabits per second, and 24-39GHz towers can cover a mile radius at up to 3Gbps. Real world performance depends on many many factors, but DSL performance can be similarly degraded from it’s theoretical maximum.

i compared with mm wave 5g because it requires same density of deployment as DSLAMs for proper performance, if not higher.

like how many UEs are sharing spectrum. Which is usually a lot

totally.
