If IPFS becomes famous to the point governments have to look at it, and that it allows to bypass laws, they will try to forbid by law people to run nodes, same way with Tor in some countries.
Try and succeed are different things. The larger the use case set, the tighter the integration with everything else, the stronger the reliance on it, the harder it will be to outlaw it. Often the laws drift ever-so-slightly to accommodate the new reality.
If you put it on IPFS, it's not "your data" any longer. If that doesn't work for you, then don't use IFPS.
Edit: I do get why people are concerned about persistence of bad stuff. But it's not at all unique to IPFS. And even IPFS forgets stuff that nobody is serving. I mean, try to find these files that I uploaded a few years ago: https://ipfs.io/ipfs/QmUDV2KHrAgs84oUc7z9zQmZ3whx1NB6YDPv8ZR... and https://ipfs.io/ipfs/QmSp8p6d3Gxxq1mCVG85jFHMax8pSBzdAyBL2jZ.... As far as I can tell, they're just gone.
