Even then, I don't know how you solve the problem of transmission monopolies.
I think the only solution is when customer can buy from multiple generators and brokers

There's a few options for natural monopolies. Regulated standards and practices, and tarrifs can be effective. Public ownership can be effective. Mandating divestiture can be effective.
A market works pretty ok for generation. Although, a system operator that coordinates to provide stability seems like a requirement.
I think there's potential for a market approach in long distance transmission; the operator could identify unmet transmission needs (sector A often has excess/curtailed generation, sector B often has excess/curtailed loads; maybe we should increase transmission capacity through those links), and run a bid process to solve those needs. I think the high price to build long distance transmission means you do want to have coordinated planning though: you don't want to massively overbuild transmission capacity on one path.
Lots of countries have nationalised the transmission network (while leaving the fully or partially privately run), which seems to work reasonably well.
To your point, I don't think making physical electrical conductors communal property would be anything less than a disaster. That conductors are most valuable when you have a grid makes the monopoly problem structural in my opinion.
I suspect from the indifference to the details and heavy-handed tone of the article that there is some particular agenda. Saying utilities are just greedy is not very compelling when the legal conditions on their operations are much more complex than most compabies to say the least.
