Unfortunately the problem with low density, ribbon development of our countryside isn’t just the ribbon development. You have been able to “better your lot” specifically because people like me stayed in Dublin; while my lot got worsened because people like you moved to the countryside.
Every move to the country means that it’s more difficult (if not impossible) to have properly functioning towns and cities. Public transport won’t work as it should as we don’t have the critical mass of people in our cities to make it profitable. The same is true for hospitals and centres of excellence, leading to a scenario where we have five hospitals in County Mayo to serve a county population of 130,000. “Centres of excellence” became a dirty phrase, but when you have a life threatening illness, where would you prefer to go to - the specialist in a centre of excellence who deals with illnesses like yours every day, or a rural GP who might see one case a decade? Increased urbanisation would result in fewer hospitals but better healthcare. The same is true for internet availability - lower capital costs and potentially faster broadband. The same is true for a Cork-Limerick-Galway counterbalance to an ever-expanding capital. The same is true for the arts, theatre, galleries. For universities. For the cost and supply of utilities: electricity, water, gas. For the viability of small towns (if you need to get in your car to drive to the shop, you’re as likely to drive 15 minutes to the nearest “big” town as you are 5 minutes to the local corner shop). For getting businesses to not only want to locate in Dublin.
We’re all interconnected whether we like it or not. Solar panels and driverless cars and teleworking won’t solve all the problems. Sometimes decisions need to be taken for the good of society, rather than the good of individuals. Choosing to live in the countryside isn’t a decision that only affects you, your kids and your ten rows of carrots. No man is an island. Not even those that live on one.
