Why:
Get new high efficiency heat pumps, heat pump water heater(s), electric stove range and oven, electric dryer, 4 PowerWalls + 15kW solar (25kW solar or more if you have a medium electric car commute, 45kW solar or more if your spouse also has a medium electric car commute), and a frequency slave-synchronizing manual start diesel backup generator for extended storms and extended power outages, and then disconnect your utility. Have them take the electric meter and gas meter out, and cap the gas at the property line so it doesn't leak (have a good plumber or the utility do that). If they won't let you disconnect, then find out what kind of plan you can get with the least bill (maybe electric-only, gas-only, whatever; maybe get a senior on a low cost plan to keep the monthly bill down), and disconnect everything.
You will own your own energy. No one else controls your energy. Go as far as you like. Heat your home up as much as you want.
If you live in a place that doesn't need humidity to prevent fires, then add even more solar, a treated potable water tank, and an optimized water condenser (optimized to produce as much water as possible), which will collect enough water from the air for you to drink and have some showers. This will reduce your water usage, and if you use graywater treatment and filtering from your shower and laundry, you can use that to water your lawn. That will get you in the door of hedging water utility dependence; if they start to over-charge, you can increase your solar and water condenser collection.
That would leave you with only garbage and sewer collection bills. I don't see a way around those in a modern society.
I can't say any of this has near term financial benefits. But it will remove your dependence on most utilities, practically every utility that doesn't deal with waste. If you have a lot of land, you can farm grass, animals, and if you want, vegetables. You might even have septic in a rural area. Then all you'd need are roads, firemen, hospital, doctors, ambulance, and sheriff, and you can make friends with them, and also you would still need the refuse dump service.
It's about owning your own destiny.
I don't think it's optimal, but take from it what you will. See if you want any of that independence, and you have it available to you. There are all sorts of opportunities here: you can build and live in places that have no utilities and still have all modern facilities at a reasonable cost, even though that was not possible before. Note that communist laws have probably tried to remove those areas from legal development, but all you have to do is pay them a couple hundred thousand in permit fees, and if you're doing that, you might as well leverage your independence in some way to make even more money. You have to be pretty creative to do all that. But I'm talking about ideas, so take from it what you will.
That's today.
In a decade, some of that will trickle down-market.
In 50 years, a lot of that will trickle down-market.
