Are you sure you are ready for a blockchain monetary system ?

When browsing through crypto forums I see lots of comments from people that bitcoin will replace fiat and we will liberate ourselves from governments and regulation.

Now my question to all of you :

Are you sure you are ready for a decentralized world ?

Im not saying this to minimize the potential of blockchain I just wonder if most people truly understand what it would mean if Bitcoin would fully replace fiat :

• No more schools, roads, libraries unless something gets crowd funded ? Not sure if this will be a succes
• No more social safety nets. You get paid what you work for. Sounds good but what if you are sick ? No taxes thats true :) What if you get fired ?
• Probably no more police or firemen. Who will pay their wage ? Also who takes the lead ? Will they fork is they have different opinions :) ?
• Who will we blame for everything :) ? If everything turns out your own fault it will be very confronting ! Maybe we can still blame some god :)

Probably Im overdoing. But did anybody think about this ?

Be carefull what you wish for :)
