Yes, data-center operators are bound to follow laws, including NSLs  
and gag orders. How about your ISP? Is it bound to follow laws,  
including NSLs and gag orders?

Do you think everyone should run a full node behind TOR? No way, your  
repressive government could just block TOR:

Or they could raid your home and seize your Raspberry Pi if they  
couldn't read your encrypted internet traffic. You will have a hard  
time proving you are not using TOR for child porn or cocaine.

If you are living in a country like this, running Bitcoin in an  
offshore VPS could be much easier. Anyway, Bitcoin shouldn't be your  
first thing to worry about. Revolution is probably your only choice.

Data-centers would get hacked. How about your Raspberry Pi?

Corrupt data-center employee is probably the only valid concern.  
However, there is nothing (except cost) to stop you from establishing  
multiple full nodes all over the world. If your Raspberry Pi at home  
could no longer fully validate the chain, it could become a  
header-only node to make sure your VPS full nodes are following the  
correct chaintip. You may even buy hourly charged cloud hosting in  
different countries to run header-only nodes at negligible cost.

There is no single point of failure in a decentralized network. Having  
multiple nodes will also save you from Sybil attack and geopolitical  
risks. Again, if all data-centres and governments in the world are  
turning against Bitcoin, it is delusional to think we could fight  
against them without using any real weapon.

By the way, I'm quite confident that my current full node at home are  
capable of running at 8MB blocks.
