Thor's abilities are magical in nature and have been shown to completely override natural/science based abilities. i.e. his control over the weather supercedes Storm's, and his control over magnetism trumps magneto's for this reason. I don't see any reason why protex's control over his molecules would be better than say, magneto's control over magnetism. Mjolnir is a massively powerful magical object- he also used it to cut off juggernaut from the source of his powers, and flat out reverse the process that gave hyperion HIS powers and trap him completely. Mjolnir >>> White martian by a mile.
Thor can hit/hurt intangible beings. he's done it to vision, and de-phased his body out of the ground when placed there by kitty pryde, so clearly has some control over his body's structure in that area.
There's also VERY little evidence anywhere that thor's insides are any less durable than his outsides- that is, strong enough to take hits from nuclear weapons, the core of stars, and direct hits from CELESTIALS without visible damage. If protex did somehow manage to get inside of thor without taking damage (unlikely) thor could BFR himself to the center of the sun or to muspelheim- an area of extreme heat that would purge/kill protex immediately, but leave thor unharmed.
Classic thor has many, many instances of him swinging the hammer, throwing the hammer, and using it to fly in excess of lightspeed. There's even a scan in the respect thread of Thor towing a jet at supersonic speeds using the hammer, so control isn't an issue. And...phsyically superior? are you sure? Classic thor is strong enough to immobilize an enraged hulk for at least a solid hour. The white martian is not stronger than Thor.
Telepathy is an advantage, but thor IS resistant and should protex go that route, he'll have a hard time fending off some extremely powerful attacks by Thor in the meantime- not just physical hits but lightning, godforce, anti-force, matter manipulation, hurricane force winds, and of course...flat out BFR to somewhere he couldn't survive.
The lightning based powers are another reason yes- but classic thor has a lot more in his arsenal. The guy can even time travel, though I don't see how that would help here.
