While the technology itself can't be banned, there are definitely ways the network can be restricted. We've seen miner migrations on mainnet in the past due to crackdowns, and for both Lightning and Bitcoin nodes, it's as simple as scraping explorers and "politely asking" your ISP or hosting provider to shut you down or hand over your information. "Govs doesn't give a shit about you running a node" now, but this could change in the future.

Well, if I use Tunnelsats i would use a direct connection, but you're right - it would add an extra 3-10ms of latency.

I believe you may be confusing caution with fear. Is it really so fearful to want to protect your location? I operate a public Tor node with the intention of assisting others who value their privacy, connecting with other Tor nodes, and keeping my own node anonymous. I consider all the different entities involved in handling my traffic in my threat model as well!
