That’s all well and good but blue origin has not proven the ability to be successful, even with a sub orbital joyride. Throwing money at the problem won’t solve anything, this is Amazon We are talking about, Jeff Bezos. Money isn’t the issue, it’s management, it’s pipe lining, I don’t want to say it’s talent because I know there’s plenty of talented people there. But blue origin is a laughingstock in the industry for a reason, and it’s going to take more than contracts to get them to a point where they can compete with SpaceX. They already have contracts with other private launch companies, they license out their engine, but they have been holding them back because of their constant delays. If blue origin wasn’t causing so many delays, there probably would be more substantial competition in the industry right now from other launch companies.

I don’t see how they are ready for a Mars contract within the next 10 years

In addition to what others have already said: I suspect during a proper launch SpaceX will not give 100% throttle until the rocket has at least cleared to tower.

The super heavy booster with the ship on top has a thrust to weight ratio of about 1.6. This means they can throttle down to 75% and still get the rocket off the launch table.

Apparently not.

The "special concert" was spotted still in its bags a few days ago.

The new hypothesis is that SpaceX will completely remodel the area under the launch table after the frist flight. This will include a proper deluge system and the special concert.

Yeah right on.

To understand why it's no problem as this commenter said, remember that the thrust itself is comparable to forces easily within the usual realm of civil engineering tasks.

We don't use rockets to get to space because they generate cosmically far-fetched amounts of thrust, but rather because they can generate thrust reliably and continuously over an extended period, largely indifferently to the environment around them.

It's a similar principle as how a jet liner with engines capable of transporting hundreds of people at Mach 0.9 can be held in place by a couple of wooden chocks.
