What do you mean by compete? Militarily? Economic?
Norway has the second highest GDP per-capita (after Luxembourg) and third highest GDP (PPP) per-capita in the world. Not a part of the EU.
Military competition wouldn't matter in a state of heavily armed, nuclear neutrality. Lower taxes and cut red tape to allow more businesses from all over the globe to set up here = economic growth. Once other countries establish valuable economic links, military action is highly unlikely to ever occur, especially with our current defensive pacts.
Economical advantages? Care to elaborate? All I've seen are higher taxes to fund the EU...
Open borders can be negotiated through bilateral treaties.
If we want to support other countries we can voluntarily give aid, we don't need it taken from us through extra taxes.
We already have 'stricter rules'. They override our homemade ones and follow a legal structure completely alien to the Common Law.
EDIT: Just re-read this and apologies if it seems a tad agressive

Norway realized they like the way they live their life and don't need help from others to stay stable. Do you think other EU countries before joining the EU were as stable as Norway, or on their way to becoming as stable? Not really. Most of them needed to rely on each other, even since the world wars. Norway and Switzerland just decided they don't want to make sacrifices for benefits because they wouldn't actually benefit much, since they're very successful on their own. Again, even since the world wars.
Your idea about wars is actually great, but it's not about wars with other countries around the world, but about preventing european countries from starting a war between themselves. With EU now, a chance of a war between european countries is very slim.
Other countries (like my home country, Slovenia) benefit much from being part of the EU, though many people complain about the prices skyrocketing because of the euro (seriously, everything is double than before we joined), but overall, the Euro (currency) is supposed to be very stable.
Perhaps you haven't seen any economical advantages, but without the EU, the disadvantages (and the taxes with them) would probably be much higher.
Open borders are meh for me. Same thing as before, really, I don't give a damn, travelling was easy back then too.
But overall, I agree that the Britain got screwed over. You never actually needed help, but unfortunately for you, your leaders were always people-persons and were glad to give a hand to other nations I guess

And they naturally assumed you people could afford to give a penny or two more for the poorer nations. I guess you could've stayed like Norway (hell, you kept your superior currency), but instead chose to share that superior currency with others.
Though I don't see much bad about the EU, not from my point of view or from many other countries'. But you still got screwed over

Although, think what it would be like if Britain didn't join. The EU would be weaker, many nations would still be poor, and everyone would think you're assholes.
